Currently, the most common materials of the brake cylinders and clutch cylinders on the market are iron and aluminum, and there are also plastics. However, plastic products are easy to wear and have a short service life.
The surface treatment methods used for products of different materials are different. For iron products, our main surface treatment method is electrophoresis. For aluminum products, we can do surface heat treatment according to customer needs, such as Sand Blasting, Original Oxidation, Hard Oxidation, and Dacromet.
The surface treatment of all products is actually to increase the internal and external hardness, thereby extending the service life of the products. However, each heat treatment method has its own advantages, and the price is naturally different. Customers can choose according to their needs. The following is our general introduction to the products after different heat treatments, hoping to help you understand these heat treatments and distinguish them.
The main advantages of Electrophoresis: It can prevent iron rust, discoloration, and corrosion.
The main advantages of Sand Blasting: It can improve the fatigue resistance of the product, extend the durability of the coating film, and is also conducive to the leveling and decoration of the coating.
The main advantage of Original Oxidation: The surface of the product after the original oxidation is very close to the OEM one.
The main advantages of Hard Oxidation: It can increase the surface hardness of the product. It has high wear resistance, strong adhesion, good insulation, and non-toxic. (The oxidation time determines whether the surface color of the product is dark or light. The longer the oxidation time, the darker the surface color.)
The main advantages of Dacromet: It has strong corrosion resistance, high heat resistance, good recoating performance, and the surface looks smoother.
