Processing: It is possible to harden other metals by melting and incorporating antimony and antimony alloys. You can harden your lead alloys with our Super Hard alloy, which melts at only 750 F, rather than using Antimony, which melts at more than 1100 F.


Babbitt Bearing Alloys

Coined from the name of Isaac Babbitt, the white metal alloy got its name in Babbitt in 1839. Other white metals containing tin, copper, and antimony have been referred to as Babbitt over time. you can occasionally replace tin with lead. Is Babbitt metal an alloy?

Babbitt Bearing Alloys

Usage:Babbitt metal, also spelled Babbitt Metal, is any of several tin- or lead-based alloys used as bearing material for axles and crankshafts.

Bearing Pouring Instructions

No oil can seep between the liner and shell of the bearing because of the babbitt, which we must carefully pour into a dense, solid mass. When the Babbitt and shell do not have a solid bond, oil seeps in, and hydrostatic pressures build-up, causing the babbitt to vibrate and eventually crumble as a result.

Select the correct babbitt and pour your bearings as follows to ensure long-life bearings:

  • Clean the Bearing Shell

Remove foundry scale, dirt or rust with grinding wheel, sand blast, file, wire brush, or by chipping. Remove all oil or grease, either by burning or by scouring with hot caustic solution. (If caustic is used, rinse thoroughly with hot water.)

  • Heat the Bearing Shell
If the shell has been heated to remove oil, no further heating may be needed. Otherwise, heat to about 500?F., being careful to heat evenly. Remove any soot with wire brush.

  • Apply flux
Apply flux to the surface of the bearing shell and immediately rub with a bar of Tin or 50/50 Solder. Work as fast as possible–use flux liberally. As soon as each area has been covered with tin or solder and while the shell is still hot, scrub the surface with a soft wire brush. This bonds the tinning material to the bearing shell
  • After Tinning Is Completed

While still hot, wipe surplus flux and tinning alloy from surface with a woolen cloth.

  • Stir Babbitt
To ensure uniform temperature throughout, stir the metal thoroughly from bottom to top. Skim dross from surface.
  • Use Large Ladle
If possible, use a ladle large enough to pour the entire bearing at one dipping. If not possible, use two ladles, pouring simultaneously. Immerse ladles in babbitt pit for five minutes before pouring, to properly heat them.
  • Continue To Add Babbitt
As the babbitt begins to shrink down into the bearing, continue to add molten metal to prevent formation of shrinks and to assure a denser mass. Pouring temperatures listed in the descriptions are subject to variation depending on size of bearing and temperature of bearing shell.




Usage:whether you need it for the creation of custom alloys or any other purpose. Bismuth metal is 99.99% pure.
Specifications:They sell their bismuth in pound-sized chunks. You can rest assured that this is one of the best bismuth metals on the market.



Usage:They make custom anodes in various sizes and alloys and the standard Hull Anodes available.


Aluminum anodes meet the current MIL-A-24779 standard, while zinc ones meet the current MIL-A-18001K standard (ASTM B-418 Type 1).

The lead time for aluminum anodes is between two and three weeks. You would have to provide the dimensions, quantity, and alloy needed via fax, email, or phone.


Bullet Casting Alloys

Usage: Bullet Casting Alloy consists of 2% tin, 6% antimony, and 92% lead – also known as “hardball” bullet casting alloy. You are purchasing 10lbs of this bullet alloy ingot, so if you need a total of 20lbs, simply order a quantity of 2 for this item. Casting your bullets has numerous advantages, regardless of whether you’re a hunter or just shoot for fun.
Shipping And Customer feedback:They appreciate reviews. As a result of these and other publications, they’ve been able to get some press for our casting alloys. Shipping is free for any order over $149.
At Rotometals, you’ll find everything from bullet lead alloys to linotype alloy ingots to casting retainer putty and more. Custom blends and lead-free bullet alloys are also available.



Feature Of  99.99% Pure Bismuth Metal
Usage:Reloaders can now use a Bismuth Shot alternative that is lead-free and non-toxic. For waterfowl and upland game birds, Rotometals Bismuth Shot is an excellent alternative to lead shot. Bismuth Shot from Rotometals is a superb alternative to lead-free ballast weight and has a density similar to lead.

You can still use the Bismuth shot in a variety of ways! Like those on a golf ball, the small satellites or tails on BBs help reduce air drag by making them less sticky in the air. Bismuth Shot is the only non-toxic shot that performs as close to lead as any other non-toxic shot.

Accessibility:Very few Bismuth Shot manufacturers produce “perfectly round” rounds today.

  • Zinc Anodes


  •  Anodes protect buried or submerged metal structures from corrosion. A sacrificial zinc anode works by “sacrificing” itself between two other metals. The anode will corrode before the other two metals. Anodes are used in many applications, from boats to offshore pipelines, and should be changed annually.
  • Rotometals provide high-quality zinc anodes. They also have zinc ingots, cast rods, extruded rods, and wire.
  • Over 70% of North American zinc die castings use Zamak 3 ingots. From Zamak 3 to Zamak ZA 8 ingots, we guarantee you won’t find better zinc products at better prices. Shop their zinc metal products today!

  • Zincs-Pencil/Engine

Sacrificial anodes, pencil anodes, and engine anodes are all terms for zinc rods that are consumed by electrolytic action to protect your expensive equipment from damage and deterioration, and corrosion.

Frequently Asked Questions

#1- Can I return something I don’t want?

Yes, they will deduct our shipping costs from your refund. It is 30 days return/exchange policy. Restocking fees apply to all refunds/exchanges.

#2- Does your free shipping cover all orders?

Free shipping applies to website orders of $149.00 (USD) or less for small items that fit in 12″ or smaller boxes. Larger items like zinc and lead sheets, boat and pot anodes, and lead bricks are exempt from free shipping rules. Anything marked “free freight” or “freight included” ships free. Orders placed by phone, fax, or email do not qualify for free shipping. Free shipping is only for US orders.

#3- Can I get my metal quicker?

They always do their best to get it out to you within 24 hours if you select a defined shipping service speed during checkout.

#4- What is the hardest metal?

Tungsten is the strongest natural metal in terms of the tensile strength (142,000 psi). But tungsten is a brittle metal that shatters on impact. Titanium has a tensile strength of 63,000 psi.

#5- What affects an alloy’s hardness?

Carbon content, grain size, and alloying elements can all be used to calculate the hardenability and rate of austenite transformation. Carbon provides hardness, while alloying elements determine how deep it occurs.

#6- Do you ship internationally?

They only ship to Connecticut law enforcement and active military personnel; they do not ship to other states. They cannot ship to APOs.

#7- How does AR500 Armor protect against multiple hits, single hits, and stabs?

Body armor AR500 usually outperforms the industry standard in multi-hit capability in the rated calibers. Ceramic and Kevlar, for example, are more easily damaged when struck in the face. It frequently loses material and becomes useless after a few rounds. Due to its advanced steel core, AR500 Armor loses very little material after a strike. Instead of the steel core, we use a protective coating on the exterior to reduce spall and fragmentation. This increases our armor’s Multi-Hit capability while extending its lifespan.

#8- Is my privacy guaranteed?

Your personal information is kept strictly confidential and will not be used in ways you have not consented to. They will also never sell your information to a third party.

We will be happy to hear your thoughts
