The difference between forged aluminum alloy wheels and other wheels and the supporting situation of forged aluminum alloys in the market.

PART ONE

Casting Process VS Forging

craft

Cast aluminum alloy wheels are made by casting molten aluminum water in a sand mold, and then machining (deburring, trimming, polishing) after cooling and forming. Forging is to use a steel mold, place a heated and softened aluminum block in it, shape it by forging, and then machine it after cooling.

Casting workpieces are prone to porosity, looseness, slag inclusion, and coarse grains. During the forging process, due to the continuous forging and pressing of the aluminum block, after forming, its molecular structure will become very tight, and the grains will be finer and more uniform. Forged aluminum alloy wheels have better strength and can withstand higher pressures, so under the same size and strength, forged wheels are also lighter than cast wheels.
Due to the fine grain size of the forging, if the wheel is also polished, the forged aluminum alloy wheel looks smoother and brighter than the cast aluminum alloy wheel.

Advantages of steel wheels
1. Lightweight and save fuel

Forged aluminum alloy wheels are made of high-strength aluminum alloy materials. After forging and heat treatment, under the conditions of the same specifications and the same bearing capacity
fuel consumption savings

carbon emissions reduction

2. Good heat dissipation ➡ Extend wheel life
Forged aluminum alloy wheels are made of high-strength aluminum alloy materials. After forging and heat treatment, under the conditions of the same specifications and the same bearing capacity
The heat dissipation coefficient of aluminum alloy wheels is three times that of steel wheels

Service life of brake pads and tires

Effectively control the rapid increase in tire pressure

Guaranteed driving safety

3. High dimensional accuracy ➡ Good dynamic balance performance
Ensure that product functional dimensions meet high precision requirements

Processed by high-precision CNC turning center

During the machining process, one clamping completes the turning of the mounting surface and the contour surface to ensure the coaxiality of the mounting hole and the tire mounting surface

It can effectively reduce the jitter caused by high-speed driving and improve the comfort of the whole vehicle

4. Effectively reduce the wear of the wheel ➡ prolong the service life of the wheel
Mounting tires for aluminum alloy wheels

good dimensional accuracy

good runout error

Good dynamic balance performance

Reduce wheel rotation resistance

Reduce the friction between the tire and the ground

5. Safe, no fire hazard

When the wheel fails or other reasons cause friction between the wheel and the body or both wheels, the aluminum alloy material does not produce sparks. To avoid accidents caused by sparks of oil burning or even vehicle combustion, especially in natural gas transport vehicles and oil tankers, in addition to the use of aluminum alloy wheels, a large part of the entire vehicle adopts an all-aluminum alloy structure.

6. Good corrosion resistance
When aluminum alloy wheels fail: basically no corrosion

Aluminum alloy wheels

The nature of aluminum is lively and it is easy to react with oxygen to form a dense aluminum oxide layer on the surface.

➡Alumina is very stable and not easy to be corroded

➡Alumina layer will act as a protective layer

Prevents the aluminum inside from further reacting or corroding

steel wheel

After the paint peels off, the steel immediately reacts with oxygen, and the rust layer formed after the steel is oxidized is very loose.

➡It will increase moisture absorption and water absorption to accelerate the internal oxidation rate

7, beautiful and generous

8. High recycling rate

Aluminum is called "the metal that never dies". Because of the dense oxide protective film on the surface of aluminum, it is extremely resistant to corrosion and will not rust.

In theory, it can be fully recycled for recycling, and the quality and performance of recycled aluminum and primary aluminum are no different.

Aluminum alloy wheels are green metal products that save energy and reduce emissions.
