The material formula of the car hub comprises the following components in percentage: 6.0-8.0% of Si, 0-0.10 % of Fe, 0.4-0.6% of Cu, 0.02-0.04% of Mn, 0.4-0.6% of Mg, 0.04-0.06% of Cr, 0.02-0.04% of Ni, 0.04-0.06% of Zn, 0.03-0.05% of Sn, 0.12-0.16% of Ti, 0.03-0.05% of Pb and 90.24-92.9% of Al.
Description
Technical field
The present invention relates to material formula, be specifically related to a kind of car hub and material formula.
Background technology
Wheel hub is very important crucial structure the in the automobile, material requirements to wheel hub is: proportion is little, in light weight, heat conductivity is good, thermal expansion coefficient is little, enough mechanical strengths and high temperature strength are arranged, have that wear-resisting, withstanding corrosion, dimensional stability are good, casting and machinability be good, and productive costs is low.Production practice for many years prove that all the wheel hub of selecting the Al-Si alloy casting for use satisfies above-mentioned requirements substantially.But intensity and the safety of people in order further to improve and improve wheel hub still constantly explored new material, new process so far.
Summary of the invention
The objective of the invention is to: improve a kind of sedan car hub material formula, utilize sedan car hub material formula of the present invention to make car hub, improve the mechanical strength and the high temperature strength of car hub, strengthen wear-resisting, decay resistance, strengthen the safety performance.
The technical scheme that technical solution problem of the present invention is adopted is: in order to improve the mechanical strength of car hub, choose reasonable best material formula.
This sedan car hub material formula is made up of following percentum: Si6.0～8.0%, Fe0～0.10%, Cu0.4～0.6%, Mn0.02～0.04%, Mg0.4～0.6%, Cr 0.04～0.06%, and Ni 0.02～0.04%, Zn0.04～0.06%, Sn0.03～0.05%, Ti 0.12～0.16%, Pb0.03～0.05%, and Al 90.24～92.9%.
Beneficial effect of the present invention is: proportion is little, in light weight, heat conductivity is good, thermal expansion coefficient is little, mechanical strength and high temperature strength have been improved, have that wear-resisting, withstanding corrosion, dimensional stability are good, casting and machinability be good, low cost of manufacture, safety performance height.
