Overview

High temperature resistant copper gaskets are widely used in sealing parts of pressure vessels, valves, cylinder heads with high temperature, high pressure, and strong corrosiveness, as well as in industries such as automobiles, railway locomotives, ships, steel mills, mines, power plants, chemical equipment, and engineering machinery.

Product Details

High temperature resistant copper gaskets are usually made of pure copper and have high thermal and electrical conductivity. They are commonly used in high-temperature environments, such as automotive engines, electronic devices, industrial machinery, etc., for the purpose of filling, isolating, or conducting heat.

The characteristics of these copper gaskets include:

High temperature resistance: Copper gaskets can maintain stable performance in high temperature environments and are not easily softened or deformed.

Good thermal conductivity: As copper itself is a good thermal conductive material, copper gaskets can effectively conduct heat and help dissipate heat.

Conductivity: Copper is a good conductive material, so copper pads also have good conductivity.

Mechanical properties: Copper gaskets usually have a certain degree of flexibility and elasticity, and can adapt to certain pressures and deformations.

When choosing high-temperature resistant copper gaskets, specific working environments, temperature requirements, pressure requirements, and usage requirements need to be considered to ensure the selection of appropriate specifications and models.

When ordinary copper is heated in a reducing atmosphere containing hydrogen or carbon monoxide, hydrogen or carbon monoxide easily reacts with cuprous oxide (Cu2O) at grain boundaries, producing high-pressure water vapor or carbon dioxide gas, which can cause copper to fracture. This phenomenon is often referred to as the "hydrogen disease" of copper. Oxygen is harmful to the weldability of copper. Bismuth or lead forms low melting point eutectic with copper, causing copper to become thermally brittle; When brittle bismuth is distributed in a thin film at grain boundaries, it causes copper to become cold brittle. Copper gaskets have excellent conductivity, thermal conductivity, ductility, and corrosion resistance. Instrument sealing gasket, heat-resistant copper gasket

Pure copper is a purple red metal, commonly known as "purple copper", "red copper" or "red copper". Copper is highly ductile. Pure copper, the size of a drop of water, can be pulled into fine threads up to two kilometers long or rolled into almost transparent foil larger than a bed. The most valuable property of copper is its excellent conductivity, second only to silver among all metals. But copper is much cheaper than silver, so it has become the "protagonist" of the electrical industry.
