Brass castings are mostly valve bodies. Castings have strong corrosion resistance and are made of many materials. ) Copper castings play a huge potential role in the development of modern technology, whether it is a spacecraft entering space or an intelligent When robots enter the deep sea, whether it is the rapid updating of computer equipment or the rapid development of engineering science and technology, it is inseparable from the use and support of high-quality castings. Most cast copper alloys (cast copper parts) cannot be heat treated to strengthen

but are used in the cast state. However, there are also a few cast copper alloys that are used after heat treatment. For example, beryllium bronze, chromium bronze, silicon bronze and some high copper alloys are heat treatment strengthened alloys. In addition
