3003 aluminum alloy is used for truck car fenders

What is a car fender?

Fenders are usually installed behind the four tires of the car, with the front two fixed on the left and right lower sills, and the rear two fixed on the rear bumper. There are mainly aluminum alloy fenders, cowhide fenders, plastic fenders, rubber fenders, etc.

What is the function of car fenders? As the name suggests, car fenders are used to block mud.

1. Fenders can protect mechanical structures and prevent rust.

2. Fenders can also protect car paint.

3. Fenders can block mud and rain.

4. It can reduce the number of car washes.

Aluminum alloy car fenders are mainly made of 3003 aluminum alloys , which belongs to the AL-Mn alloy series. It is a widely used rust-proof aluminum with higher strength than industrial pure aluminum, good corrosion resistance, good weldability, and poor cutting performance.

Mechanical properties of 3003 aluminum plate:

Tensile strength σb (MPa) 140-180

Conditional yield strength σ0.2 (MPa) ≥115
