Introduction of 7050 T7451 aluminum block bar plate
7050 T7451 aluminum block bar plate is a high-strength heat-treatable alloy with extremely high strength and resistance to spalling corrosion and stress corrosion cracking. Commonly used in aircraft structural parts for medium and thick plate extrusions, free forgings and die forgings. The alloy requirements for the manufacture of such parts are: resistance to spalling corrosion and stress corrosion cracking, fracture toughness and fatigue resistance.
The main alloying element of 7050 series aluminum alloy is zinc. Adding magnesium to the alloy containing 3%-75% zinc can form MgZn2 with ficant strengthening effect, so that the heat treatment effect of this alloy is far better than that of aluminum-zinc binary alloy. The content of zinc and magnesium in the steel, the tensile hardness will have to be further improved, and its resistance to stress corrosion and spalling corrosion will increase accordingly. After heat treatment, very high strength characteristics can be achieved. This series of materials generally will be added in a small amount Alloys such as copper and chromium. In this series, 7050 T7451 aluminum block bar plate is the top grade, which is known as the best product among aluminum alloys. It has high strength and is far better than mild steel. This alloy has good mechanical properties and anode reaction. Mainly used Used in aerospace, mold processing, machinery and equipment. Tooling and fixtures, especially for aircraft manufacturing structures and other high-stress structures that require high strength and strong corrosion resistance.
