The Preferred Structure Of Aircraft Aluminum Alloy 7A09
Among the aluminum materials for aerospace vehicles in China, 7A09 alloy is one of the preferred high-strength alloys for the main stressed structural parts. The semi-finished products available include plates, strips, bars, profiles, thick-walled tubes, forgings, etc. The chemical composition is more reasonable than that of 7A04 alloy, so it has superior comprehensive performance and becomes one of the designer's main materials. Its chemical composition (mass%): 0.5Si, 0.5Fe, (1.2—2.0) Cu, 0.15 Mn, (2.0-3.0) Mg, (0.16-0.30) Cr, (5.1-6.1) Zn, 0.10Ti, other impurities are individually 0.05, totaling 0.10, and the rest is Al.

7A04 Alloy - Yield Strength Close To Tensile Strength
7A04 alloy is an Al-Zn-Mg-Cu series heat-treatable aerospace super-hard aluminum alloy, which can be heat-treated and strengthened. Its composition has been listed in GB/T3190-2008, and it is compatible with the B95 alloy of the Soviet Union and Russia and the AlZnMgCu1 of Germany. .5.3.4365 alloy is equivalent, because in 1944 the Soviet Union’s 95th factory successfully trial-produced this alloy semi-finished product, hence the name B95 alloy. In 1957, China Northeast Light Alloy Co., Ltd. (then Harbin Aluminum Processing Plant) produced this alloy with the help of Soviet experts. Alloy plates and extruded materials.

The Difference Between High Speed Steel And Tungsten Steel
High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as wind steel or front steel, which means that it can be hardened even if it is cooled in the air during quenching, and it is very sharp. It is also called white steel.
