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.
