C86500 Is a kind of copper alloy material, mainly used in chemical machinery and equipment, with high electrical conductivity, thermal conductivity, corrosion resistance and mechanical strength characteristics. C86500 Copper by adding the right amount of tin, zinc and other elements, significantly improve the corrosion resistance and mechanical strength of the material, so that it can maintain long-term stability and durability in the face of common acid, alkali, salt and other corrosive media in the chemical environment . In addition, C86500 copper material also has good processing performance, suitable for Leesh sand casting, investment casting, forging, and machining processes, can meet the needs of complex chemical equipment.

What is the investment casting advantages?

1-Smooth surface finish Use the Aluminum mould and wax to make the pattern, then glue with the silica sol as binding agent, so you will see a very clear difference compare with Sand Casting .Mostly the roughness range from Ra 1.6 μm to Ra6.4 μm, but Leesh Engineering Investment Casting service can achieve a average above 3.2μm. 2-Save machining Time and
