When it comes to brass materials, 351 brass stands out for its excellent machinability and corrosion resistance, making it a popular choice for various applications. Here's a buying guide to help you choose the right 351 brass for your project:
1. Material Composition:
- 351 brass, also known as C351 brass, is a leaded brass alloy composed primarily of copper and zinc, with the addition of lead for improved machinability. The lead content typically ranges from 1.5% to 3.0%, enhancing the alloy's chip formation and lubricity during machining processes.
2. Machinability:
- One of the key advantages of 351 brass is its superior machinability compared to other brass alloys. The presence of lead in the alloy reduces friction and heat generation during machining, resulting in smooth chip formation and improved tool life. This makes 351 brass an ideal choice for applications that require intricate machining operations, such as precision components and fittings.
3. Corrosion Resistance:
- 351 brass offers good corrosion resistance, making it suitable for use in environments where exposure to moisture, chemicals, or harsh weather conditions is a concern. The alloy forms a protective oxide layer on its surface, preventing corrosion and prolonging the lifespan of components made from 351 brass.
4. Applications:
- Due to its excellent machinability and corrosion resistance, 351 brass finds applications in various industries, including automotive, plumbing, electrical, and marine. Common applications include bushings, fittings, valves, fasteners, electrical connectors, and decorative hardware.
5. Size and Form:
- 351 brass is available in a variety of sizes and forms to suit different project requirements. It is commonly available in round bar, hexagonal bar, square bar, and sheet/plate forms. Choose the appropriate size and form of 351 brass based on your specific machining or fabrication needs.
6. Supplier and Quality:
- When purchasing 351 brass, ensure to source it from reputable suppliers known for their quality and reliability. Look for suppliers that offer certified materials and provide technical support to assist with material selection and machining processes.
By considering these factors, you can confidently choose the right 351 brass for your project, ensuring optimal performance, machinability, and corrosion resistance for your application requirements.
