Oxygen-free copper
It is pure copper that does not contain oxygen or any deoxidizer residue. But it actually still contains very trace amounts of oxygen and some impurities. According to the standards, the oxygen content is not greater than .3, the total impurity content is not greater than .3, and the purity of copper is not greater than . According to the oxygen content and impurity content, oxygen-free copper is divided into No. 1 and No. 2 oxygen-free copper. The purity of No. 1 oxygen-free copper reaches .3, the oxygen content is not more than .3, and the total impurity content is not more than .3. The purity of No. 2 oxygen-free copper reaches ., the oxygen content is not more than .3, and the total impurity content is not more than .3. Oxygen-free copper has no hydrogen embrittlement, high electrical conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance. Oxygen-free copper plate and strip are key materials in the vacuum industry. Electric vacuum devices such as high-power transmitter tubes, magnetrons, traveling wave tubes, vacuum capacitors, vacuum switches, etc. all need to be operated at high temperatures of ℃ in a hydrogen atmosphere. During brazing, hydrogen and oxygen in copper will react + rrr+, and the water vapor generated will cause intergranular cracks in the copper material, causing leakage of vacuum parts. Therefore, countries around the world specifically stipulate oxygen-free copper. Special varieties have strict regulations on oxygen content. The oxygen content in my country's No. 0, No., and No. oxygen-free coppers are stipulated as For each grade, the oxygen content is respectively b, B and other elements, in order to ensure the high conductivity of oxygen-free copper, the impurity content must be strictly controlled. The national standard for the copper content in oxygen-free copper stipulates that the copper content in oxygen-free copper No. 0, No. 0 and No. 1 oxygen-free copper are respectively stipulated as., .,.The electrical conductivity of oxygen-free copper products should reach.

Usage: Can be used to make various deep-drawn and bent stress-bearing parts, such as pins, rivets, washers, conduits, air pressure gauges, screens, radiator parts, etc. It has good mechanical properties
,
It has good plasticity in the hot state and acceptable plasticity in the cold state. It has good machinability, is easy to weld and weld, and is corrosion-resistant. It is a common brass variety that is widely used. .
Feature introduction: Brass is an alloy of copper and zinc. The simplest brass is a binary alloy of copper and zinc, which is called simple brass or ordinary brass. Brass with different mechanical properties can be obtained by changing the zinc content in brass. The higher the zinc content in brass, the higher its strength and slightly lower plasticity. The zinc content of brass used in industry should not exceed
. Any higher zinc content will cause brittleness and deteriorate the properties of the alloy. In order to improve certain properties of brass, brass that adds other alloying elements to unary brass is called special brass. Commonly used alloying elements include silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass and slightly reduce the plasticity. Brass containing aluminum less than
has good overall properties such as processing and casting. The tin added to brass can significantly improve the brass's ability to resist seawater and marine atmosphere corrosion, so it is called navy brass
. Tin can also improve the cutting performance of brass. The main purpose of adding lead to brass is to improve the machinability and wear resistance. Lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance. Adding aluminum to manganese brass can also improve its performance and obtain castings with smooth surfaces. Brass can be divided into two categories: casting and pressure processing products. The product specifications are complete, the price is favorable, the packaging is intact, the copper is pure, the straightness is good, the inventory is large, and the material certificate and report can be provided.
