1. What aluminum casting alloy you can get from aluminumcasting-China?
Alloy A356.0 and A357.0 are our main aluminum casting alloys.
2. What casting process we have?
The permanent mold casting (Gravity die casting) and low pressure die casting.
3. What other service we can provide?
Except aluminum casting, we can provide casting heat treatment, casting machining or machining directly from solid bar (Aluminum alloy 6061-T6, 316 stainless steel, copper alloy of C38500, etc), surface finish treatement ( anodize, passivation, nickel plating, chromium plating, zinc plating, silver coating, PTFE based solid film lubricant coating).
4. What quality control for our products?
Raw material control including chemical composition, mechanical properties, NDT for aluminum castings, the third party test for the surface treatment to meet your specifiaction.
5.What is anodizing?
Anodize is a coating of aluminum oxide that is grown from the aluminum by passing an electrical current through an acid electrolyte bath in which the aluminum is immersed. The coating thickness and surface characteristics are tightly controlled to meet end product specifications. Aluminum oxide is an extremely hard material that approaches the hardness of a diamond. As a result, the aluminum oxide layer provides excellent wear and corrosion protection.
6.What is the purpose of anodizing?
General reasons for anodizing are: wear resistance, corrosion resistance, surface lubricity, heat dissipation, dielectric (non-conductive) properties, adhesion, and aesthetics.
7.Is anodizing environmentally friendly?
Yes, anodize does not entail the use of heavy metals nor does it produce toxic waste. Anodize meets the environmental and safety directives of the FDA, USDA, ELV, WEEE and RoHS.
8.Will anodizing hide scratches?
Anodizing will provide minimal cover-up for surface scratches because anodize mimics original substrate finish. To further enhance anodize appearance consider aggressive etching, hand polishing, or surface blasting.
