Abstract
The invention discloses a free-cutting and corrosion-resistant lead-free brass alloy. The brass alloy is composed of following components in percentage by mass: 55-65% of Cu, 0.2-2.5% of Mg, 0.3-2.0% of Sb, 0.5-1.0% of Sn, 0.002-0.3% of Ca, 0.1-0.5% of Re, 0.2-0.9% of other elements and the balance of Zn; and the other elements refer to at least two of Ti, Al, Si, B and Ni. The alloy provided by the invention has good cutting property, high strength and excellent corrosion resistance, and is a novel environment-friendly material for replacing lead-containing brass. The alloy provided by the invention is widely applied to the production of parts for a drinking water pipeline system, such as a gate valve, a faucet and the like, and is widely applied to the production of products such as toys, household appliances and the like.
Description
Technical field
The present invention relates to field of alloy material, more particularly, relate to the lead-free free-cutting corrosion resistant brass alloy.
Background technology
Brass alloys are widely used in various fields; Mostly brass alloys of the prior art are the Winn bronze alloy; It is the necessarily deficiencies that exist aspect cutting ability, intensity and solidity to corrosion more; Particularly the Winn bronze alloy is not an ep-type material, can not be applied to the field that drinking water pipeline etc. has environmental requirement.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that exists in the prior art, and a kind of lead-free free-cutting corrosion resistant brass alloy is provided.
Lead-free free-cutting corrosion resistant brass alloy of the present invention; Be achieved through following technical proposals; Form according to said mass percent by following component: Cu 55-65%, Mg0.2-2.5%, Sb 0.3-2.0%, Sn 0.5-1.0%, Ca 0.002-0.3%, Re 0.1-0.5%, other element 0.2-0.9%, surplus is Zn; Other element is Ti, Al, Si, B, at least two kinds of elements among the Ni.
Alloy of the present invention has good cutting performance, and high intensity and solidity to corrosion (seeing the following form 1,2) are the novel environment-friendly materials of a kind of alternative Winn bronze.Alloy of the present invention is widely used in the drinking water pipeline system and makes gate valve, and parts such as tap are in the products such as toy and household electrical appliance.
The no leaded brass of this research of table 1 and Winn bronze C3604 mechanical property and machinability
No leaded brass of this research of table 2 and Winn bronze C3604 solidity to corrosion
