Main Parts and Materials of Automobile

In order to meet the requirements of energy saving, environmental protection, safety and comfort, and to achieve the goal of lightweight, high strength and high performance, the automobile materials have changes a lot.

According to the materials composition, automobile materials are usually divided into metal materials and non-metal materials. With the development of automotive technology, composite materials and nanomaterials will be widely used.

Autobody

• High strength steel sheet
• Aluminium alloy
• Magnesium and Titanium alloys
• Foam alloy plate
• Engineering plastics
• High strength fiber composites
• Ceramic material

Engine

• Engine hood: Low carbon steel/ high strength steel/ aluminum alloy/ composite material/ magnesium alloy
• Engine cylinder block: The material of cylinder block should have enough strength, good casting sex and cutting sex, and the price should be low, therefore, the commonly used material is cast iron, alloy cast iron.
