Yesterday I picked up...I saw a free pick up on a forum. 5 KG of Babbitt and 2.5 KG of lead. Lead is lead... But the Babbitt bronze is.... Our Grade 2 Babbitt is an alloy made up of 89% tin, 7.5% antimony, and 3.5% copper. Grade 2 Babbitt is generally used as a sacrificial layer for bearings among other things. Meets ASTM B23 specification. Our Babbitt is sold in 7 lb ingot form, so if you need one 7 pound ingot simply add a quantity of 1 to your cart. Please see the product images - there is a detailed certificate of analysis available for viewing. | 89% Tin | 7.5% Antimony | 3.5% Copper | Dimension 13'' X 2'' X 1.25'' | Solidus (F) - 466 | Liquid (F) - 669 | Pouring Temperature (F) - 795-805 | Density (lbs/in3) - 0.2667 | Specific Gravity (g/m3) - 7.39 | Brinell Hardness - 24.5/12 | Tensile Strength (lbs./in.2) - 9,200 | Elongation % - 8.0 | Compressive Strength (tons/in2) - 6.44 |
I have a few 7" gemstone faceting laps made from left over 11R white metal: Tin 89.5%, 7.75% Antimony and 2.75% copper, after they were machined, I cast the lathe swarf into a 2" copper tube to make a mallet. It was used a lot on conrod bearings of large marine diesels. Peter, the guy I learnt foundry work off, did this reline of a bronze prop shaft bush with 11R: it's been 8 years in the water on a fishing boat and there's almost no lube oil consumption in use and is holding up really well. It was machined with a diamond honed, razor sharp positive rake carbide tool so the crystal structure gets exposed when a truly sharp tool cuts the metal without smearing the surface
