Cold extrusion process is the production of aluminum oxide embossed aluminum, the press metal mold blank at a constant speed strong pressure embossed aluminum oxide at room temperature, specializing in the production, forcing the metal to plastic deformation extruded from the die cavity , to obtain the required shape, dimensions and certain mechanical properties of extrusion. "As gas water heater is working with the water, so most of its operating temperature between 110 degrees Celsius to 260 degrees Celsius. Hot state, annealing and quenching conditions forming the new performance is better than the heat treatment significantly enhanced the effect, but the heat treatment process demanding. This paper relies on this technique to study the structure and mechanical properties of the microstructure of thin-walled copper and aluminum pipe plug-in resistance pressure welding joint interface organization. Aluminum and aluminum alloy sheet can be tungsten or tungsten AC TIG pulse welding. Benefits 1 aluminum-magnesium alloy melt cost only aluminum die-casting production efficiency 2/3 2 25% higher than the aluminum oxide embossed aluminum, metal casting than aluminum high 300-500K, LFC 200% higher than aluminum magnesium castings 3 surface quality and appearance significantly better than aluminum (thermal load is reduced because of mold embossed aluminum oxide price can be reduced inspection frequency) 4 die life is two times that of aluminum (or more, according to the cavity shape) 5 Mg off ramp chess angle may be small (to cancel subsequent machining), and the surface forming good (because of low viscosity magnesium) embossed aluminum oxide, aluminum oxide embossed dealers, rolls Alcoa (certified merchants) from Jinan Heshun Aluminum Co., Ltd. provided.
