Inherent Quality Analysis an d Research on Famous Automobile Wheel Hubs

This paper presents the application of A356alloy wheel hub which is produced by electrolyzing low Ti-Al base alloy,and also presents analysis of structure and properties of wheel hub product,and comparisons between domestic wheel hub products and famous foreign products.The researches show that mechanical properties of wheel hub made by electrolysis low Ti-Al base alloy can match with those of Benz counterpart,13.25%improvement than BMW wheel hub and6.9%improvement than Audi wheel hub.The wheel hub made by electrolysis low Ti-Al base alloy shows good mechanical properties,better match of strength and toughness,better uniformity of composition and structure,fine micro grains,round and integrity of silicon phase after heat treatment ,normal distribution dimple of cross-section.
