Abstract

The invention discloses bronze alloy for casting parts. The bronze alloy comprises, by weight, 9-12 parts of silicon, 87-92 parts of copper, 5-8 parts of tin, 14-18 parts of chromium, 11-15 parts of nickel, 7-10 parts of iridium, 6-9 parts of molybdenum, 8-11 parts of zinc and 4-7 parts of manganese. By the arrangement, the bronze alloy is good in corrosion resistance, good in wear resistance, good in heat resistance, high in mechanical strength, good in toughness, high in hardness and long in service life.

Description

A kind of casting process component bell metal

Technical field

The present invention relates to alloy field, be specifically related to a kind of casting process component bell metal。

Background technology

In recent years, Chinese Foundry equipment industry achieves swift and violent development, mo(u)lding equipment, coremaking equipment, sand preparing machine, casting equipment etc. all achieve significant progress in properties of product, reliability, automaticity etc., and progressively stride forward to Green foundry direction。

Often there is flaw because of various situations in carrying out process of manufacture in the parts material of the various product used in prior art, and the mechanical strength of founding materials and performance can not get ensureing, cause that product is easily worn, hardness is not high, not corrosion-resistant, brittle, service life is short。

Summary of the invention

It is an object of the invention to provide and a kind of adopt silicon, copper, stannum, chromium, nickel, iridium, molybdenum, zinc and nine kinds of one-tenth of manganese to be grouped into, have that corrosion resistance is good, wearability is good, heat-resist, mechanical strength is high, good toughness, hardness big, the casting process component bell metal of the feature of long service life。

The technical scheme is that, a kind of casting process component bell metal, described casting process component bell metal is grouped into by silicon, copper, stannum, chromium, nickel, iridium, molybdenum, zinc and nine kinds of one-tenth of manganese, in described casting process component bell metal, parts by weight shared by each composition are respectively as follows: described silicon and account for 9-12 part, described copper accounts for 87-92 part, described stannum accounts for 5-8 part, described chromium accounts for 14-18 part, described nickel accounts for 11-15 part, described iridium accounts for 7-10 part, described molybdenum accounts for 6-9 part, and described zinc accounts for 8-11 part, and described manganese accounts for 4-7 part。

In a preferred embodiment of the present invention, in described casting process component bell metal, parts by weight shared by each composition are particularly as follows: described silicon accounts for 10 parts, described copper accounts for 88 parts, described stannum accounts for 6 parts, and described chromium accounts for 15 parts, and described nickel accounts for 12 parts, described iridium accounts for 8 parts, described molybdenum accounts for 7 parts, and described zinc accounts for 9 parts, and described manganese accounts for 5 parts。

In a preferred embodiment of the present invention, in described casting process component bell metal, parts by weight shared by each composition are particularly as follows: described silicon accounts for 11 parts, described copper accounts for 91 parts, described stannum accounts for 7 parts, and described chromium accounts for 17 parts, and described nickel accounts for 14 parts, described iridium accounts for 9 parts, described molybdenum accounts for 8 parts, and described zinc accounts for 10 parts, and described manganese accounts for 6 parts。

Of the present invention is a kind of casting process component bell metal, the present invention adopts silicon, copper, stannum, chromium, nickel, iridium, molybdenum, zinc and nine kinds of one-tenth of manganese to be grouped into, and has that corrosion resistance is good, wearability is good, heat-resist, mechanical strength is high, good toughness, hardness are big, the feature of long service life。

Detailed description of the invention

Below presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining。

Of the present invention is a kind of casting process component bell metal, described casting process component bell metal is grouped into by silicon, copper, stannum, chromium, nickel, iridium, molybdenum, zinc and nine kinds of one-tenth of manganese, in described casting process component bell metal, parts by weight shared by each composition are respectively as follows: described silicon and account for 9-12 part, described copper accounts for 87-92 part, described stannum accounts for 5-8 part, described chromium accounts for 14-18 part, described nickel accounts for 11-15 part, described iridium accounts for 7-10 part, described molybdenum accounts for 6-9 part, described zinc accounts for 8-11 part, and described manganese accounts for 4-7 part。

Further, in described casting process component bell metal, shared by each composition, parts by weight are particularly as follows: described silicon accounts for 10 parts, and described copper accounts for 88 parts, and described stannum accounts for 6 parts, described chromium accounts for 15 parts, and described nickel accounts for 12 parts, and described iridium accounts for 8 parts, described molybdenum accounts for 7 parts, and described zinc accounts for 9 parts, and described manganese accounts for 5 parts。

Further, in described casting process component bell metal, shared by each composition, parts by weight are particularly as follows: described silicon accounts for 11 parts, and described copper accounts for 91 parts, and described stannum accounts for 7 parts, described chromium accounts for 17 parts, and described nickel accounts for 14 parts, and described iridium accounts for 9 parts, described molybdenum accounts for 8 parts, and described zinc accounts for 10 parts, and described manganese accounts for 6 parts。

Proportioning is carried out so that the functional alloy property height obtained differs by each composition Different Weight percentage ratio。

The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope that disclosed herein; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention。Therefore, protection scope of the present invention should be as the criterion with claims protection defined。
