Brass Nuts
Material: Generally, it is lead brass, such as H59, H62, etc., which is made by mixing copper and zinc.
Characteristics
- Not easy to rust and corrosion-resistant, suitable for humid or marine environments.
- Strong thermal and electrical conductivity, ideal for electronic devices and conduction applications.
- Low strength and hardness, not suitable for high-load-bearing applications.
- Golden yellow appearance with good decorative properties.
- Good machining performance, easy to cut and stamp into shape.
Types and Uses of Brass Nuts
- Hexagon Nuts: The most common type, used for various mechanical connections and fastenings, such as faucets, valves, mechanical assemblies, etc.
- Knurled Nuts: With external knurling, they are mainly used in hardware products such as hardware springs, special-shaped springs, and decorative art springs. The operation mode is mostly injection molding.
- Injection Molded Nuts: Also known as embedded nuts or insert nuts, they are widely used in industries such as mobile phones, laptops, and various plastic shells. They are fixed inside plastic parts by embedding them after heating or through mold injection molding.
SuSpecifications and Standards of Brass Nuts
- Size Specifications: The inner diameter of the nuts ranges from M1.2 to M24 or even larger, such as the common M2, M3, M4, M5, M6, etc., and there are also British imperial sizes like 1/4, 3/8, etc.
- Standards: Common ones include the national standards GB/T809, GB41, GB6170, etc., as well as American standards, British standards, Japanese standards, etc. Different standards vary in dimensions, tolerances, performance, etc.
Production and Processing of Brass Nuts
- Production Process: It includes casting, forging, machining, etc. Casting is suitable for the production of nuts with complex shapes; forging can improve the strength and performance of the nuts; machining is used for the manufacture of nuts with high precision requirements.
- Surface Treatment: Generally, no treatment is required, which can maintain the original color and performance of the brass. It can also be treated by nickel plating, chrome plating, etc., to improve corrosion resistance and decorative properties.
