China has developed a new generation of high-strength aluminum alloy fasteners
Recently, HJYJ Fastener Systems Corporation, a leading fastener technology manufacturer in China, announced:
The new generation of high-strength aluminum alloy fasteners developed by the company have been successfully applied in the aviation and aerospace fields.
The new generation of high-strength aluminum alloy fasteners are lightweight, high-strength, and highly reliable.
High strength aluminum alloy fasteners are the world's first high-strength aluminum alloy fastener product with a strength level of up to 600MPa. The technical level is internationally leading and can comprehensively replace carbon steel fasteners used for installation and connection of instrument brackets. The self weight is lighter, and the weight reduction effect exceeds 60%, greatly improving the lightweight level of fasteners.
High strength is not the end point of fastener development. We want it to be both strong and tough. In addition to optimizing the structural design, the team has also established comprehensive mechanical performance indicators for fasteners such as tensile strength, yield strength, reduction of area, elongation, and impact toughness, defining the upper and lower limits of fastener tensile strength, and improving the toughness of the new generation of high-strength aluminum alloy fasteners.
