The common metal washers materials are stainless steel, carbon steel, copper, aluminum and titanium. Among them, stainless steel washers are represented by 304 and 316 models, which have good anti-corrosion and anti-rust properties; Carbon steel wahers has high strength, but attention should be paid to anti-corrosion; Copper washer has good thermal conductivity, suitable for specific industries; Aluminum washers are lightweight and corrosion-resistant, suitable for applications such as micro motors. Titanium washers are high strength, lightweight corrosion resistance.
1.Stainless steel washer
Stainless steel washers are very common. Stainless steel washers are the most representative models 304 and 316, which have excellent corrosion and rust prevention properties. 304 stainless steel washers contain 18% to 20% chromium and 8% to 10% nickel, making them stable in a variety of environments. The 316 stainless steel washer adds molybdenum to improve durability in highly corrosive environments such as seawater. These gaskets are widely used in machinery and equipment, food processing equipment and other industries, especially in high temperature and high pressure environments, their sealing performance is particularly excellent.
2.Carbon steel washer
Carbon steel has high strength and good workability, so carbon steel gaskets can remain stable under greater pressure. However, carbon steel washers are prone to rust in a humid or corrosive environment, so attention should be paid to anti-corrosion measures when used. They are commonly used in equipment with high concentrations of acid and alkali solutions.
3.Copper washer
Copper washers also have a place in hardware stores. Copper has good thermal and electrical conductivity, as well as good corrosion resistance. This makes copper gaskets in electronic equipment, communication equipment and other industries have a wide range of applications. Compared with stainless steel and carbon steel, copper washers cost less, but their hardness and strength are also relatively low, so they are not suitable for overly complex mechanical equipment.
4.Aluminum washer
Aluminum washers are also popular in hardware stores because of their light weight and corrosion resistance. Aluminum washer is suitable for micro motor, all kinds of mechanical equipment and other fields. Aluminum washers cost less and weigh less than copper washers. In addition, aluminum also has good processing properties and can be customized according to needs.
5. Titanium washer
Titanium washers are renowned for their exceptional strength, lightweight properties, and superior resistance to corrosion. Made from high-grade titanium, these washers are ideal for applications where durability and longevity are critical, such as in aerospace, automotive, and marine environments. Their non-corrosive nature ensures that they maintain integrity and performance even under extreme conditions, including exposure to saltwater and corrosive chemicals. Additionally, titanium washers offer excellent heat resistance, making them suitable for high-temperature operations. Whether used in precision engineering or heavy-duty applications, titanium washers provide a reliable solution for securing components with added resilience against environmental challenges.
In summary, the common metal gasket materials in hardware stores mainly include stainless steel, carbon steel, copper and aluminum. These washers have their own characteristics and are suitable for different industries and application scenarios. At the time of purchase, consumers should choose the appropriate gasket material according to the specific needs and use environment.
