Zinc alloy die waterway _ wealth (certified) _ Shenzhen zinc alloy die

 Tungsten steel sheet has been excellent hardness, high hardness, wear resistance, good high elastic modulus, high compressive strength, chemical stability (acid, alkali, high temperature oxidation), low impact toughness, low coefficient of expansion, thermal conductive alloy with iron and characteristics similar. Silicon steel, cold rolled zinc alloy die-casting, suitable for the production drawing dies, wear parts and stamping parts and carbide core with automatic presses, etc., using the strength and impact toughness, wear resistance lower than the above-mentioned alloy. Top load large forging dies, such as for screws, rivets and other top die, but also for stamping die. Extrusion die. Aluminum die-casting molds blanking electrochemical surface hardening aluminum die in neutral system anodized accumulation constitute class ceramic composite conversion film amorphous skills, capabilities, tracing, composition and structure of the film began to explore film formation process and mechanism. Skills, research results show that the neutral Na_2WO_4 mixed system, the control film accelerator concentration of 2.5 ~ 3.0g / l, the concentration of agent network constitutes 1.5 ~ 3.0g / l of zinc alloy die master, Na_2WO_4 concentration of 0.5 to 0.8 g / l of zinc alloy die, the peak current density of 6 ~ 12A / dm ~ 2, zinc alloy die Shenzhen weak agitation, lack of uniformity can be obtained without gloss good gray series inorganic non-metallic film. The film thickness of 5 ~ 10μm, the hardness of 300 ~ 540HV, excellent corrosion resistance. The neutral system for aluminum has better adaptability, a variety series aluminum rust-proof aluminum, wrought aluminum, etc. can better film.
