  • Aluminum and aluminum alloy knowledge introduction

    Aluminium alloy forging Fang was informed that aluminum is a light metal, low density (2.79/Cm3), which has good strength and plastic, aluminum alloy has goodstrength, aluminum alloy strength up to 600Mpa, the tensile strength of commonaluminum alloy is up to 200-450Mpa, it is much higher than steel than steel,therefore widely used in the manufacture of machinery. The conductivity after the silver and copper aluminum, ranking the third, used in the manufacture of variouswire. Aluminum has good thermal conductivity, can be used as a cooling material.Aluminum has good corrosion resistance and good plasticity, suitable for all kinds of pressure processing. Aluminium alloy forging Fang said aluminum alloy processing methods can be divided into deformation of aluminum alloy and castaluminum alloy. Deformation of aluminum alloy is divided into non heat strengthened aluminum alloy and aluminum alloy heat treatment reinforcement.Non heat strengthened not to improve mechanical properties after heat treatment,only through the cold working deformation to achieve enhanced, it mainly includesthe high pure aluminum, industrial high purity aluminum, industrial pure aluminumand rust proof aluminum. Heat strengthened aluminum alloy can improve the mechanical properties by quenching and aging heat treatment, it can be divided into aluminum, aluminum forging, super hard aluminum and special aluminum alloy.Aluminium alloy forging Fang said aluminum alloy can obtain good mechanical properties with heat treatment, physical properties and corrosion resistance.According to the chemical composition can be divided into aluminum silicon alloy,aluminum alloy casting Al Cu alloy, aluminum magnesium alloy and aluminum zinc alloy.

    1 pure aluminum products of pure aluminum smelting products division andpressure processing products of two categories, the former is represented by thechemical composition of Al, the latter with Pinyin LG (aluminum, industrial use) said.

    2 pressure processing aluminum alloy aluminum alloy pressure processingproducts are divided into rust (LF) and hard (LY), forging (LD), super hard coating(LC), (LB), special (LT) and brazing (LQ) and other seven categories. Commonly used aluminum alloy material condition for the annealing (M bank), atherosclerosis(Y), (R) and other three kinds of hot rolling.

    3 aluminum aluminum and aluminum alloy processed into a certain shape of the material referred to as aluminum, including plate, belt, foil, tube, rod, wire, etc..

    4 casting aluminum alloy casting aluminum alloy (ZL) according to the mainelements other than silicon, copper aluminum, magnesium, zinc is divided into four categories, code is respectively 100, 200, 300, 400.

    5 high strength aluminum alloy high strength aluminum alloy to aluminum alloytensile strength greater than 480 MPa, is the pressure processing aluminum alloyduralumin alloy, super alloy and casting alloy.
