Description
(1) technical field
The invention belongs to wheel hub material technical field, particularly to a kind of aluminum alloy wheel hub material.
(2) background technology
At present, domestic wheel aluminium alloy mainly uses A356 alloy (the domestic trade mark: ZL101A), contains in its chemical composition
Have: Si7%, Mg0.35%, Fe < 0.2%, Cu < 0.2%, Zn < 0.1%.Owing in low-quality aluminium alloy ingots, iron content is higher,
And along with the reuse of alloy furnace charge and the use of Iron reutilization, instrument, top set part etc. in producing, make alloy iron-holder continue
Increase.And ferrum is a kind of main objectionable impurities in Cast aluminium alloy gold, along with the increase of iron content, can shape in metallographic structure
Pin that the hardness of one-tenth own is the highest, lamellar short iron phase, its existence has been isolated the matrix of aluminium alloy, has been reduced the mechanical property of alloy
Can, especially toughness, and make part machinery difficulty of processing increase, cutter, cutlery serious wear, dimensional stability is deteriorated.Therefore,
Continuing a kind of new aluminum alloy wheel hub material, reasonably combined by each composition of indispensable element, prepared mechanical property is higher, processing
Performance and mechanical performance more preferable aluminum alloy wheel hub material, to adapt to the car industry high request to hub for vehicle wheel material.
(3) summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of mechanical property being effectively improved aluminium alloy and
The processing characteristics of product and the aluminum alloy wheel hub material of mechanical performance can be greatly improved, solve and ask present in prior art
Topic.
The present invention is achieved through the following technical solutions:
A kind of aluminum alloy wheel hub material, is made up of the chemical composition of following percentage by weight:

0.2-0.4%, Fe ＜ 0.12%, Sr 0.02-0.04%, Re 0.2-0.4%, Zr 0.01-0.04%, remaining is Al.
Preferably, in this aluminum alloy wheel hub material, Sr 0.02-0.04%, Re 0.2-0.4%, Zr0.01-0.04%.
In aluminium alloy wheel hub material chemical composition of the present invention, control strict to Fe, eliminates its adverse effect, to alloy
Corrosion resistance tool has significant improvement；By adding mischmetal Re, strontium Sr, tri-kinds of elements of zirconium Zr with scientific and reasonable ratio
Example (Re 0.2-0.4%, Sr 0.02-0.04%, Zr 0.01-0.04%) mixes with other elements, the impurity in enabling aluminum alloy to
Phase FeAl, AlFeSi etc. form polynary metallic compound so that it is morpho logical thinning and nodularization, thus can be effectively improved aluminium alloy
Mechanical property and Product processing performance；To 0.4-0.6%, this aluminum alloy wheel hub material is made to have by improving magnesium Mg content in material
Have lightweight, plasticity good, tensile strength high；To 0.2-0.4%, wheel hub is improve by increasing titanium Ti content in material
Hardness and the advantage of tensile strength.This aluminum alloy wheel hub material is reasonably combined by above-mentioned each composition, the final aluminum prepared
Alloy wheel hub material mechanical property, processing characteristics and mechanical performance are excellent.
