The density of pure aluminum (ρ = 2.7g / cm3), about 1/3 of iron, low melting point (660 ℃), aluminum is face-centered cubic structure, it has a high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), ease of processing, can be made into a variety of profiles, sheet metal, good corrosion resistance. But the strength of aluminum is very low, annealed σb value of approximately 8kgf / mm2, it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually adding alloying elements and heat treatment and other methods to strengthen the aluminum scrap price of copper ash, which has been a series of aluminum alloy. Add some elements to form the alloy while maintaining the advantages of lightweight aluminum with high intensity while, σb values ??of up to 24 ~ 60kgf / mm2. This makes the "specific strength" (strength and weight ratio σb / ρ) is better than a lot of steel, an ideal structural material, widely used in machinery manufacturing, transportation machinery, power machinery and aviation industries, the aircraft fuselage , skin, compressor, etc. often aluminum to reduce weight. Aluminum instead of steel materials, welding, structural weight can reduce more than 50%. Hydrogen is easily absorbed molten aluminum. Unfortunately, Zaozhuang copper ash, hydrogen solubility is substantially greater than the solubility of the molten aluminum in the solid aluminum. When the price of aluminum alloy solidification copper ash, hydrogen discharged from the melt, shrinkage porosity expanded and enlarged, accompanied by the loss of mechanical properties. Hydrogen general charge from wet and humid melting tool, but the main source of hydrogen is moisture in the environment. Because almost difficult to prevent adsorption of hydrogen smelting, it is necessary to remove hydrogen from the melt before pouring. The most commonly used method is to melt into the drum to dry nitrogen or argon bubbles. The use of chlorine to remove hydrogen is particularly effective. However, due to environmental and safety reasons often preclude its use in production. Copper ash recovery | Zaozhuang copper ash | Sun Shine scrap metal recycling (view) recovered from the Linyi City Shengxin scrap metal Limited. Linyi City Shengxin scrap metal recycling Ltd. (shengxin.tz1288.com) is a professional, "scrap metal, alloy, machine aluminum, brass, wine together, miscellaneous aluminum, copper ash, zinc ash, zinc slag" of the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "lead ingots, scrap metal, alloy, machine aluminum, brass, wine together, miscellaneous aluminum, copper ash, zinc ash, zinc "brand has a good reputation.
