Aluminum alloy as a typical lightweight metal is widely used in foreign automobiles, foreign automobile aluminum alloy components mainly include piston, cylinder head, clutch housing, oil pan, bumper, heat exchanger, bracket, wheels, body plate and decorative parts. First, material characteristics: 1. Light weight and high strength: aluminum is lighter than traditional steel, so it can reduce the overall weight of the vehicle and improve fuel efficiency.At the same time, the strength of aluminum profiles is also very high, which can meet the needs of auto parts in different working conditions. 2. Corrosion resistance: Aluminum profiles have good corrosion resistance, which can prevent auto parts from rusting and corrosion in humid environments.This makes aluminum profiles more durable in automotive manufacturing, extending the service life of the car. 3. Good thermal conductivity: aluminum profiles have good thermal conductivity, which can quickly conduct heat to the external environme…
