Washers are divided into various types including flat washers, spring washers, anti-loose washers, and special purpose washers such as sealing washers. These components serve to protect connected surfaces, prevent fastener loosening, and provide other specialized functions.
Flat Washers: Typically used between connection parts to increase contact area, disperse pressure, and prevent damage to softer materials.
Spring Washers: Made from 65Mn (spring steel) with heat treatment hardness of HRC44-51HRC and oxidized surface. These provide additional friction between nuts and bolts to prevent loosening.
Lock Washers: Feature a unique design with two washers - one with radial convex surfaces and one with bevel tooth surfaces. When assembled, this configuration creates lifting tension that prevents loosening under vibration.
| Automotive | Used in high-strength applications such as engines and heavy-duty machinery for their superior support area and anti-loosening performance. |
| Mechanical | Applied in mechanical, electronic, and construction fields for connecting various components including circuit boards, engines, and building structures. |
| Energy | Utilized in power generation equipment and transmission line connections within the energy industry. |
| Architectural | Essential for construction projects, shipbuilding, and petrochemical equipment to ensure structural integrity and operational safety. |
- Aluminum: Excellent thermal/electrical conductivity but requires careful processing due to softness.
- Titanium: Best processed with EDM machining using deionized water to control heat.
- Steel: High strength often requires wire cutting for complex features due to heat generation.
- Brass: High tensile strength but requires slow cutting speeds due to softness.
- Non-metal Washers: Polymer-based for superior sealing and shock absorption in pipeline systems and electronics.
- Metal Washers: High strength and corrosion resistance for high-temperature, high-pressure applications.
- Composite Washers: Combine metal and non-metal benefits for chemical and food processing equipment.
Aluminum Characteristics: Lightweight (2.7 g/cm³), corrosion-resistant, good conductivity, 100% recyclable, highly formable, and non-magnetic.
