Abstract

A low-Cu alloy able to be cut at high speed contains Cu (55.0-58.0 wt.%), Pb (2.5-3.5), Fe (0-0.35) and Zn (rest). Its preparing process includes smelting, casting, rolling at 720-750 deg.C and drawing at 60 m / min. Its advantages are compact structure, fine and ordered crystal grains and high machining performance.

Description

Technical field: [0001] The alloy material and its processing method of the present invention, in particular, an alloy material mainly composed of copper material and its processing method. Background technique: [0002] Chinese Invention Specification (CN1080768C) discloses a copper alloy and a production method thereof. A copper-based alloy mainly composed of about 0.1-1.5% (weight) of tin, about 0.01-0.35% (weight) of phosphorus, about 0.01-0.8% (weight) of iron, about 1.0-15% (weight) of zinc and The balance being substantially copper, the alloy contains phosphide particles uniformly distributed throughout the matrix, the phosphide particles having a finer component of phosphide particles and a coarser component, the finer component of phosphorus The particle size of the compound particles is 0.075-0.5μ. The preparation method is to homogenize the above-mentioned raw materials at a temperature of 537.8-787.8°C at least once, each time for at least one hour; rolling to ...
