Sliding Copper High Strength Bushing Sleeve Thin Walled 35x40x35 25x30x30

Sliding Copper high-strength bushing sleeve thin-walled 35*40*35 25*30*30.

Description

The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.

Bushings are used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, various types of machine tools and interchangeable mechanical transmission connections.

Copper-based alloys with a certain amount of other elements added. Copper alloy has medium strength, easy processing, relatively fatigue resistance, beautiful color, and good electrical conductivity, thermal conductivity and corrosion resistance. It is an important branch of heavy non-ferrous metal materials.

Copper alloys are better electrical conductors. The conductivity of pure copper is between 100% and 103% IACS (see copper for the definition of IACS). The addition of any solid solution alloying element will reduce the electrical conductivity of copper, and the reduction in unit atomic concentration mainly depends on the effect of alloying elements on the copper lattice, and increases with the increase of the addition amount in the solid solution range.

Strength Copper alloy has medium strength, and the tensile strength of industrial pure copper in annealed state is about 240MPa. The strength of copper alloys can be improved by means of solid solution strengthening, work hardening, precipitation hardening (including metastable decomposition), grain refinement and dispersion strengthening. Cold working can be used alone to harden alloys or in combination with precipitation hardening or metastable decomposition to achieve strengthening.
