Zinc Considered commercially pure, this material is 99% zinc. Use it as an alternative to lead for sound barriers and vibration dampers, as well as for EMIRFI shields and architectural sheeting.
Inquire NowDie casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity. The mould cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mould during the process. Most die castings are made from nonferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and

Inquire NowTo enhance copper recovery, drossed lead bullion is treated by adding sulphurbearing materials, zinc, and/or aluminium, lowering the copper content to approximately 0.01%. During the fourth step, the lead bullion is refined using pyrometallurgical methods to remove any remaining nonlead saleable materials e.g., gold, silver, bismuth, zinc
Inquire NowCopper Casting Problems Copper in its pure form is quite difficult to cast and is prone to surface cracking, porosity problems, and to the formation of internal cavities. The characteristics of the metal for the purpose of casting can be improved by adding small amounts of elements including silicon, nickel, zinc, chromium, tin and silver.

Inquire NowThis ratio of~ 87.25% Bismuth, 0.75% Antimony and 12% Tin is the best ratio we have come up with as a substitute for lead. This alloy melts at about 395 F and is best cast or poured at about 500F. Testing the hardness with a Lee Hardness Testing Kit, we came up with an average of 19.3 on the Brinnell Hardness Scale, although there was a range during the testing.
