[pic] • What is an alloy? An alloy is a mixture or metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure, while partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on …

Why Diamond has higher melting point than Silicon …

Neither diamond nor silicon carbide melts at standard pressures. > However, they both sublimate at high temperatures. Structures Both diamond and silicon carbide have a tetrahedral covalent network structure. Diamond Silicon carbide Physical Properties Diamond does not melt at ordinary pressures. It converts to graphite and sublimates at about 3680 °C.

Eastern Alloys - Suppliers of Kirksite alloy for sheet

Mold Base (Kirksite) Alloys. Overview. Eastern Alloys manufactures mold-base alloys, also known as Kirksite alloys. Kirksite is a moderate strength zinc-base alloy that was developed primarily as a forming tool alloy. Dies cast from Kirksite provide low-cost tooling because the alloy can be accurately cast, requiring a minimum of finishing.
