Abstract

The invention discloses a high-performance bronze alloy for casting machining. The high-performance bronze alloy is composed of nine components including copper, tin, manganese, lead, zinc, iridium, zirconium, rhenium and boron. The high-performance bronze alloy for casting machining comprises, by weight, 81-84 parts of the copper, 18-22 parts of the tin, 7-10 parts of the manganese, 5-8 parts of the lead, 9-12 parts of the zinc, 10-13 parts of the iridium, 14-17 parts of the zirconium, 6-9 parts of the rhenium and 3-6 parts of the boron. The high-performance bronze alloy is composed of the nine components including the copper, the tin, the manganese, the lead, the zinc, the iridium, the zirconium, the rhenium and the boron and has the beneficial effects of being high in mechanical strength, good in corrosion resistance and abrasion resistance, resistant to ageing, and long in service life.

Description

A kind of casting processing high-performance bell metal

Technical field

The present invention relates to alloy field, be specifically related to a kind of casting processing high-performance 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 founding materials of the various product used in prior art, causes that the mechanical strength of founding materials and performance can not get ensureing, causing that product is easily worn, easily aging, service life is short。

Summary of the invention

It is an object of the invention to provide and a kind of adopt copper, stannum, manganese, lead, zinc, iridium, zirconium, rhenium and nine kinds of one-tenth of boron to be grouped into, there is mechanical strength height, corrosion resistance is good, wearability is good, the casting processing high-performance bell metal of the feature of aging resistance, long service life。

The technical scheme is that, a kind of casting processing high-performance bell metal, described casting processing high-performance bell metal is grouped into by copper, stannum, manganese, lead, zinc, iridium, zirconium, rhenium and nine kinds of one-tenth of boron, in described casting processing high-performance bell metal, parts by weight shared by each composition are respectively as follows: described copper and account for 81-84 part, described stannum accounts for 18-22 part, described manganese accounts for 7-10 part, described lead accounts for 5-8 part, described zinc accounts for 9-12 part, described iridium accounts for 10-13 part, described zirconium accounts for 14-17 part, and described rhenium accounts for 6-9 part, and described boron accounts for 3-6 part。

In a preferred embodiment of the present invention, in described casting processing high-performance bell metal, parts by weight shared by each composition are particularly as follows: described copper accounts for 82 parts, described stannum accounts for 19 parts, described manganese accounts for 8 parts, and described lead accounts for 6 parts, and described zinc accounts for 10 parts, described iridium accounts for 11 parts, described zirconium accounts for 15 parts, and described rhenium accounts for 7 parts, and described boron accounts for 4 parts。

In a preferred embodiment of the present invention, in described casting processing high-performance bell metal, parts by weight shared by each composition are particularly as follows: described copper accounts for 83 parts, described stannum accounts for 21 parts, described manganese accounts for 9 parts, and described lead accounts for 7 parts, and described zinc accounts for 11 parts, described iridium accounts for 12 parts, described zirconium accounts for 16 parts, and described rhenium accounts for 8 parts, and described boron accounts for 5 parts。

Of the present invention is a kind of casting processing high-performance bell metal, the present invention adopts copper, stannum, manganese, lead, zinc, iridium, zirconium, rhenium and nine kinds of one-tenth of boron to be grouped into, and has mechanical strength height, corrosion resistance is good, wearability is good, the feature of aging resistance, 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 processing high-performance bell metal, described casting processing high-performance bell metal is grouped into by copper, stannum, manganese, lead, zinc, iridium, zirconium, rhenium and nine kinds of one-tenth of boron, in described casting processing high-performance bell metal, parts by weight shared by each composition are respectively as follows: described copper and account for 81-84 part, described stannum accounts for 18-22 part, described manganese accounts for 7-10 part, described lead accounts for 5-8 part, described zinc accounts for 9-12 part, described iridium accounts for 10-13 part, described zirconium accounts for 14-17 part, described rhenium accounts for 6-9 part, and described boron accounts for 3-6 part。

Further, in described casting processing high-performance bell metal, shared by each composition, parts by weight are particularly as follows: described copper accounts for 82 parts, and described stannum accounts for 19 parts, and described manganese accounts for 8 parts, described lead accounts for 6 parts, and described zinc accounts for 10 parts, and described iridium accounts for 11 parts, described zirconium accounts for 15 parts, and described rhenium accounts for 7 parts, and described boron accounts for 4 parts。

Further, in described casting processing high-performance bell metal, shared by each composition, parts by weight are particularly as follows: described copper accounts for 83 parts, and described stannum accounts for 21 parts, and described manganese accounts for 9 parts, described lead accounts for 7 parts, and described zinc accounts for 11 parts, and described iridium accounts for 12 parts, described zirconium accounts for 16 parts, and described rhenium accounts for 8 parts, and described boron accounts for 5 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。
