Die-cast aluminum & magnesium alloy series products

Aluminum-magnesium alloy with its low density and high strength has been more and more widely used, among which aluminum-magnesium alloy die-casting technology as an advanced less cutting process, with high production efficiency, saving raw materials, reducing production costs, good product performance, high precision, mainly used in electronics, automobiles, motors, home appliances and other industries. Some high-quality aluminum-magnesium alloy products with high performance, high precision and high toughness are also applied to large aircraft, ships and other industries with relatively high technical requirements. As a pioneer and participant in the field of aluminum-magnesium alloy application, Hanwang Company has done numerous research and development and tests on the surface treatment of metals in this field for many years, and now has formed a complete set of own solutions from oil removal, polishing, neutralization, ash removal, white drawing, alkali washing, passivation, sealing and so on. It can fully meet and improve the comprehensive needs of customers in performance, cost, efficiency and environmental protection.
