Abstract

The invention provides a novel environment-friendly silicon-containing alloy material tube and a preparation method thereof. The alloy material tube is composed of, by the total weight of the alloy material tube, 1-3% of zinc, 1-3% of tin, 0.5-2.5% of aluminum, 0.05-0.5% of stibium, 0.5-1% of silicon, 0-1% of titanium and the balance copper. The traditional lead element is replaced with the silicon element, zinc, tin, aluminum, stibium, silicon and copper are blended at a proper temperature according to a certain component ratio, by continuously casting a blank tube, a tin bronze tube containing the lead element can be completely replaced with the tube extruded through an extruding machine, thus, under the condition that the cost is not increased, the mechanical properties such as turningof existing tin bronze are reserved, and the requirement for the environmental protection performance of alloy is met.

Description

technical field [0001] The invention relates to the field of alloy pipes, in particular to an environmentally friendly silicon-containing novel alloy material pipe and a preparation method thereof. Background technique [0002] The existing tin bronze materials often add lead elements in order to achieve their chip-easy performance. However, with the increasing awareness of environmental protection, bronze alloys containing lead elements can no longer meet the requirements of high-end markets at home and abroad. Contents of the invention [0003] The purpose of the present invention is to provide a new type of environmentally friendly silicon-containing alloy material tube and its preparation method, which not only retains the mechanical properties of the existing tin bronze chips, but also meets the environmental protection performance of the alloy without increasing the cost. requirements. [0004] In order to realize the foregoing invention object, the technical scheme...
