7075 aluminum alloy density of 2.85, in the aerospace field is mainly used as room temperature, or 120 ℃ below the bearing with structural parts, is one of the important materials in the field. 7075 aluminum sheet as a strong alloy for commercial use at present, with high strength, corrosion resistance, good toughness characteristics, because it also has good mechanical properties and fine grain, with it can make the tool wear resistance significantly enhanced , if the thread rolling is used, the effect.
7075 is an aluminum alloy with zinc as the main alloy element, but sometimes a small amount of magnesium and copper are added. One of the super hard aluminum alloy is the alloy containing zinc, lead, magnesium and copper, close to the hardness of steel, can be heat-treated and strengthened, is a high strength, heat-treatable alloy, ordinary corrosion resistance, good mechanical properties.
7075-T651 is the top grade of 7 series, high strength, far better than any soft steel, this alloy has good mechanical properties and anodize reaction.
Especially used in the manufacture of aircraft structures and other high stress structural bodies requiring high strength and corrosion resistance.
7075 is a cold treated wrought alloy with high strength. 7075 is one of the most powerful alloys commercially available. General corrosion resistance, good mechanical properties and anodize reaction. Fine grains make depth drilling performance better, tool wear resistance enhanced, It is different from thread rolling.
