    40 to 1 bar for my trapdoor

    So far it seems great I did however make the mistake of overheating the alloy and burned the tin out of it, so it’s going to be a little softer than I planned , but should still work ok for my application. Thanks rotometals will order more.

    I am very pleased with this product, have ordered a couple hundred pounds by now, and it is always very consistent and clean. Packaging is well done, have never had any issue on delivery.
