Description

Technical Field

[0001] The utility model relates to the technical field of beryllium bronze strips, in particular to an easy-to-cut beryllium bronze strip. Background Art

[0002] Beryllium bronze alloy is an alloy with good comprehensive mechanical, physical and chemical properties. After quenching and tempering, beryllium bronze material has high strength, elasticity, wear resistance, fatigue resistance and heat resistance. At the same time, beryllium bronze also has high electrical conductivity, thermal conductivity, cold resistance and non-magnetic. There is no spark when beryllium copper material is hit. Beryllium bronze is easy to weld and braze, and has excellent corrosion resistance in the atmosphere, fresh water and sea water. Beryllium copper alloy is a rare alloy. Beryllium bronze strip can be used to make electronic connector contacts, various switch contacts, and important key components, such as diaphragm disks, diaphragms, bellows, spring washers, micromotor brushes and commutators, electrical connectors, switches, contacts, watch parts, audio components, etc.

[0003] The publication number CN 217684363 U discloses an easy-to-cut high-temperature resistant zinc-beryllium bronze belt, which relates to the technical field of zinc-beryllium bronze belts, including: a zinc-beryllium bronze belt body; a cutting groove, the cutting groove is arranged at the upper end of the zinc-beryllium bronze belt body; a first texture block, the first texture block is arranged at the upper end of the zinc-beryllium bronze belt body and is located on one side of the cutting groove; a second texture block, the second texture block is located at a position away from the first texture block on one side of the cutting groove; a trapezoidal bite groove. In fact, the practical new type prevents the disc-shaped zinc-beryllium bronze belt from becoming loose during transmission by setting a trapezoidal bite groove and a trapezoidal block. When the zinc-beryllium bronze belt is in a disc shape, the trapezoidal block is located inside one of the multiple trapezoidal bite grooves.
