Problems solved by technology

[0003] However, lead is one of the chemical substances that seriously endanger human life and the natural environment. The lead in the alloy is easily eroded or detached from the matrix during use, and the lead in industrial waste seeps into the groundwater system. Various forms of lead Enter the animal or human food chain through various channels, endangering human health and affecting the environment

Abstract

A copper-based alloy pipe containing silicon and aluminum, and a preparation method therefor. The alloy pipe consists of the following ingredients in percentage accounting for the total weight of the alloy pipe: 60 to 65% of copper, 4 to 7% of silicon, 4 to 8% of aluminum, and a remainder zinc. In the copper-based alloy, silicon and aluminum elements replace a lead element to form dispersively distributed individual phases, and the formed phases have a chip breaking effect during cutting, thereby improving the cutting treatment performance of the copper alloy and also meeting environmentally friendly and healthy standards.

Description

technical field [0001] The invention relates to the field of alloy pipes, in particular to a copper-based alloy pipe containing silicon and aluminum and a preparation method thereof. Background technique [0002] The reason why the lead-containing copper alloy has good cutting performance and anti-friction and wear resistance is mainly because lead exists in a single item in the copper alloy, which plays a good role in breaking chips during cutting; in the friction and wear environment, due to the lead The shear strength of brass is very low, and the lead on the surface of copper alloy parts makes the friction coefficient of leaded copper alloys relatively low. Therefore, lead elements are more commonly used in brass alloys. [0003] However, lead is one of the chemical substances that seriously endanger human life and the natural environment. The lead in the alloy is easily eroded or detached from the matrix during use, and the lead in industrial waste seeps into the ground...
