Abstract

The invention discloses wear-resisting aluminum alloy hardware. The wear-resisting aluminum alloy hardware comprises, by mass percent, 2.4%-2.8% of titanium, 3.2%-3.6% of iron, 0.8%-1.2% of zirconium, 1.8%-2.4% of nickel, 1.5%-1.7% of palladium, 0.6%-0.8% of carbon, 0.2%-0.4% of nitrogen, 0.3%-0.5% of oxygen, not larger than 0.1% of inevitable single impurities, not larger than 0.4% of inevitable total impurities and the balance aluminum. By means of the manner, the wear-resisting aluminum alloy hardware can have the excellent wear-resisting performance, machining is relatively simple and convenient, and the cost is low.

Description

A kind of wear-resistant aluminum alloy handware

Technical field

The present invention relates to a kind of hardware, particularly a kind of wear-resistant aluminum alloy handware.

Background technology

Present stage, aluminium alloy has become a most widely used class non-ferrous metal structured material in modern industry, in aviation, space flight, automobile, machinofacture, widely apply in boats and ships and chemical industry, along with improving constantly of present science and technology, the performance of aluminium alloy also must improve thereupon, the requirement that people are more and more higher to product could be met, and the making of all kinds of cutter adopts steel alloy mostly in hardware industry, but making processes is more difficult, and cost is high, therefore market is badly in need of a kind of wear-resisting, inexpensive, material easy to process is for making all kinds of cutter.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of wear-resistant aluminum alloy handware, can have superior wear resisting property, and processing is comparatively easy, with low cost.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of wear-resistant aluminum alloy handware, its chemical composition mass percent is as follows:

The content of titanium accounts for 2.4-2.8%, the content of iron accounts for 3.2-3.6%, the content of zirconium accounts for 0.8-1.2%, and the content of nickel accounts for 1.8-2.4%, and the content of palladium accounts for 1.5-1.7%, the content of carbon accounts for 0.6-0.8%, the content of nitrogen is 0.2-0.4%, and the content of oxygen accounts for 0.3-0.5%, and the single content of inevitable impurity is no more than 0.1%, inevitable total impurities is no more than 0.4%, and surplus is aluminium.

In a preferred embodiment of the present invention, described inevitable impurity is any one or multiple mixing in carbide, nitride and oxide compound.

In a preferred embodiment of the present invention, the summation of the content of described titanium and the content of described palladium is no more than 3.3%.

In a preferred embodiment of the present invention, the summation of the content of described iron and the content of described nickel is no more than 5.6%.

The invention has the beneficial effects as follows: the present invention can have superior wear resisting property, and processing is comparatively easy, with low cost.

Embodiment

Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

Embodiment 1:

A kind of wear-resistant aluminum alloy handware, its chemical composition mass percent is as follows: the content of titanium accounts for 2.4%, and the content of iron accounts for 3.6%, and the content of zirconium accounts for 0.8%, the content of nickel accounts for 1.8%, the content of palladium accounts for 1.7%, and the content of carbon accounts for 0.6%, and the content of nitrogen is 0.2%, the content of oxygen accounts for 0.3%, the single content of inevitable impurity is no more than 0.1%, and inevitable total impurities is no more than 0.4%, and surplus is aluminium.

Embodiment 2:

A kind of wear-resistant aluminum alloy handware, its chemical composition mass percent is as follows: the content of titanium accounts for 2.8%, and the content of iron accounts for 3.2%, and the content of zirconium accounts for 1.2%, the content of nickel accounts for 2.4%, the content of palladium accounts for 1.5%, and the content of carbon accounts for 0.8%, and the content of nitrogen is 0.4%, the content of oxygen accounts for 0.5%, the single content of inevitable impurity is no more than 0.1%, and inevitable total impurities is no more than 0.4%, and surplus is aluminium.

Embodiment 3:

A kind of wear-resistant aluminum alloy handware, its chemical composition mass percent is as follows: the content of titanium accounts for 2.4-2.8%, and the content of iron accounts for 3.4%, and the content of zirconium accounts for 1.0%, the content of nickel accounts for 2.1%, the content of palladium accounts for 1.6%, and the content of carbon accounts for 0.7%, and the content of nitrogen is 0.3%, the content of oxygen accounts for 0.4%, the single content of inevitable impurity is no more than 0.1%, and inevitable total impurities is no more than 0.4%, and surplus is aluminium.

Wherein, described inevitable impurity to be described inevitable impurity be in carbide, nitride and oxide compound any one or multiple mixing.

Be different from prior art, the present invention, by controlling iron and the total amount of palladium and the total amount of titanium and nickel, can have superior wear resisting property, add appropriate zirconium simultaneously, can reduce difficulty of processing, make processing easy, and holistic cost is cheaper.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
