Description
Technical Field

Background
Casting has been known for more than 6000 years in human history and is a method of pouring molten liquid metal into a casting mold cavity of a part of a suitable shape, and cooling and solidifying the molten liquid metal to obtain a part or a blank.
Beryllium bronze is a bronze alloy formed by adding metal beryllium into copper as a base body, and has mechanical properties, namely strength, hardness, wear resistance and fatigue resistance, which are the top of copper alloys, and electrical conductivity, thermal conductivity, non-magnetism, spark resistance and other properties which cannot be compared with other copper materials, so that the beryllium bronze is known as the 'elastic king' in the copper alloys, is widely applied to electronics, telecommunication, computers, mobile phones, precision instruments, aviation, aerospace, weapons and other military industries, and is strategic material for scientific and technical development and national defense and modern construction.
However, since metal beryllium is easy to oxidize and has active chemical properties, the direct addition of beryllium during smelting causes problems of large burning loss, low yield and the like.
