Abstract

The invention discloses a phosphor copper welding rod prepared by taken electrolytic copper, phosphorite and Yunnan tin as main raw material. The phosphor copper welding rod comprises the following elements in percentage by weight: 46.22 percent of copper, 50.53 percent of phosphorus, 2.73 percent of tin and 0.52 percent of other metal. The invention further discloses a preparation method of the phosphor copper welding rod. The phosphor copper welding rod has the benefits that the problems that an existing silver welding rod uses a large quantity of silver, the cost is high, and the environment is polluted are solved, and the phosphor copper welding rod has the advantages of relatively low melting point, high brazed rate and high welding precision and can be widely applied to the industrial manufacturing fields of refrigeration, festoon lightings, hardware appliance, instruments and meters, chemical industry, aerospace and the like.

Description

technical field [0001] The invention relates to the technical field of brazing materials, in particular to a phosphor copper electrode, and also relates to a preparation method of the phosphor copper electrode. Background technique [0002] Phosphorous copper electrodes in my country include silver-containing phosphorus copper electrodes. Silver-containing phosphorus copper electrodes are electrodes with better technological performance. Electrodes with silver or silver-based solid bodies have low melting points and good wettability. And the ability to fill gaps, can be used to braze all ferrous and non-ferrous metals except aluminum, magnesium and other low-melting point metals. This product is widely used in refrigeration, lighting, hardware and electrical appliances, instrumentation, chemical industry, aerospace, etc. Industrial manufacturing field. [0003] The characteristics of silver welding rods make people choose it for a long time, but due to the high silver content...
