Product description

This is a part used in sea vessel components, sea and fresh water heat exchanger system, the name is end cap
Adopting ZCuSn12 as the material, tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage, which can be used to produce castings with complex shapes and clear contours; tin bronze is very corrosion-resistant in the atmosphere, seawater, freshwater and steam, so it is widely used in steam boilers and seagoing ship parts;

Product features

1, in the field of silicone sol investment casting, which is considered a large product, and the product has the sealing requirements, so for the casting process control requirements are high
2, compared with the casting of steel, copper melting point is relatively low, liquefied when the mobility is relatively good, but also easy to lead to liquid metal in the mold uneven flow
3, copper in the casting process is easy to produce oxidation problems
The above characteristics lead to the low qualification rate of copper precision casting.
