Abstract

The invention provides an environment-friendly lead-free novel alloy material pipe and a preparation method thereof. The alloy material pipe is composed of the following components: zinc accounting for 1-3% of the total weight of the alloy material, tin accounting for 1-3% of the total weight of the alloy material, aluminum accounting for 0.5-2.5% of the total weight of the alloy material, antimony accounting for 0.05-0.5% of the total weight of the alloy material, silicon accounting for 0.5-1% of the total weight of the alloy material, and the balance of copper. According to the environment-friendly lead-free novel alloy material pipe, the traditional lead element is replaced by the silicon element; zinc, tin, aluminum, antimony, silicon and copper are blended in a certain ratio and continuously cast at an appropriate temperature to form a rough pipe casting; next, the rough pipe casting is extruded by an extruder to produce a tin bronze pipe completely containing no lead element; as a result, the mechanical properties, such as cutability, of the existing tin bronze are maintained without increasing cost, and the requirement on the environmental protection property of the alloy is also met.

Description

technical field [0001] The invention relates to the field of alloy pipes, in particular to an environmentally friendly lead-free new 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 an environmentally friendly lead-free new 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 that the present invention ...
