Beryllium Copper Tube

Introduction

Beryllium copper tube has better performance than other materials in strength, toughness and elasticity, so it has a broad prospect in the mold, the explosion-proof tools and wears parts.

Characteristic

The most outstanding characteristic of beryllium copper tube is the excellent flexibility, so it is also known as "King of elasticity". Its hardness is between 38-44 HRC, the thermal conductivity of 105W / m • k20 ℃, conductivity of 18% IACS, softening temperature 930 ℃, tensile strength of 1105MPa, yield strength of 1035MPa. Besides, it also has good machining performance, and is suitable for precision parts machining, improving cutting efficiency.

Process

Beryllium copper alloy is typical of aging precipitation hardening type alloy. The basic process of high strength beryllium copper is: at 760-830 ℃ appropriate incubation time (typically 25mm thickness of insulation required at least 1h), so that the full solution of solute atoms beryllium copper precursor to form a face-centered cubic lattice of α-phase supersaturated solid solution. Subsequently, at 320-340 ℃ insulation 2-3h, complete exsolution precipitation process, the formation of γ-phase (metastable phase). Which meet to form a coherent and maternal stress field and strengthen the base.
