Physical properties of aluminum and stainless steel pipes and stainless steel tube aluminum high frequency induction welding biggest problem is the impact oxides. 1) aluminum easily oxidized to Al2O3, melting point up to 2050 ℃, and the melting point of aluminum is 658 ℃, the welding, the oxide film prevents the base metal melting fused together, prone to incomplete penetration defects. 2) is similar to aluminum, when aluminum supplier, chromium preferentially than iron combines with oxygen in the surface of the base material form a dense oxide film Cr2O3 stainless w (Cr)> 12% rivets, melting point up to 2265 ℃, The melting point of chromium is 1857 ℃, there will be similar problems. Products manufactured in rolled steel molding or storage during transport, the surface will rust. Because of the corrosion layer structure with aluminum rivets loose, and the substrate attachment is not strong, and can be composed of iron oxide and aluminum primary battery, to further promote the corrosion of aluminum rivets with aluminum dealer, the coating will soon be destroyed rivets aluminum manufacturer, so it must be a net addition to painting before. Products commonly used pickling rust, it does not make aluminum deformation of the workpiece, every corner can be cleaned of rust, rust fast, relatively low-cost distributors with aluminum rivets | aluminum rivets | Heshun Alcoa Aluminum Co., Ltd. is provided by Jinan Heshun. Jinan Heshun Aluminum Co., Ltd. (www.jnhsly.com) (www.jnhsly.cn) is specialized in "aluminum, aluminum, aluminum, aluminum rod, aluminum row, aluminum, aluminum rod, aluminum elbow" of the enterprise the company of "honesty, hard service" concept, to provide you with the highest quality products and services.
