B95 Aluminium - Premium Alloy for Aerospace Applications
B95 aluminium, also known as 7075 aluminium, is a high-strength alloy primarily used in aerospace applications. It is renowned for its ability to withstand extreme conditions while maintaining excellent mechanical properties. Russian Metals supplies B95 aluminum that meets the stringent requirements of aircraft manufacturing, ensuring a reliable and durable material choice for engineers and manufacturers alike.
What is B95 Aluminium?
B95 Aluminium is a high-strength heat-treatable aluminum alloy belonging to the Al–Zn–Mg–Cu (7000 series) group. It is one of the strongest aluminum alloys used in aerospace, defense, and structural engineering applications that demand maximum mechanical performance with minimal weight.
Developed originally in Russia, B95 Aluminium is the Soviet equivalent of 7075 aluminium, known for its exceptional tensile strength, hardness, and fatigue resistance, while maintaining a relatively low density. This alloy is widely used in aircraft structures, load-bearing components, and high-performance machinery. Very high tensile and yield strength Excellent fatigue resistance under cyclic loads Good machinability and surface finish Heat-treatable for enhanced strength (T1–T6 series) Moderate corrosion resistance (often anodized or coated for protection) Low density, ideal for lightweight engineering
