Superior Corrosion Resistance

Engineered from high-grade silicon bronze alloy (C65500 or equivalent), these square punched washers excel in marine and outdoor settings due to their natural resistance to oxidation and corrosion. The smooth, uncoated finish ensures durability while maintaining a striking golden bronze color for a lasting, aesthetic appearance in various installations.

Tailored to Your Application

These washers feature a punched center hole that can be customized to precise diameters, fitting a diverse range of bolt and fastener sizes. With configurable length, width, and thickness (standard: 25 mm x 25 mm x 2 mm), they are well-suited for electrical, construction, and fastening projects, ensuring a perfect fit and secure installation.

FAQs of Silicon Bronze Square Punched Washers:

Q: How should Silicon Bronze Square Punched Washers be properly installed in marine applications?

A: For marine use, ensure the washers smooth, uncoated surface contacts both the fastening hardware and the materials to be joined. The customizable center hole accommodates various bolt sizes, and the high corrosion resistance of silicon bronze protects against seawater exposure, ensuring longevity and reliable fastening.

Q: What makes these washers suitable for electrical and construction applications?

A: Their good electrical conductivity (1417% IACS) and high tensile strength (400700 MPa) make these washers effective at maintaining secure electrical connections and withstanding structural stresses, meeting industry standards such as ASTM B96 / B98 for reliable and safe usage.

Q: When should I opt for a custom hole or washer size?

A: Select custom hole diameters or washer dimensions when your application requires non-standard bolt sizes or has unique spacing needs. This ensures a precise fit, optimizing load distribution and preventing slippage, particularly in specialized electrical or structural projects.

Q: Where are these washers typically used beyond electrical and marine applications?

A: Apart from electrical and marine sectors, these washers are used in construction (to evenly distribute load in bolted joints), general fastening solutions (to protect surfaces), and anywhere strong, corrosion-resistant hardware is needed, especially in outdoor or harsh environments.

Q: What is the process of manufacturing these washers?

A: The washers are produced using a punching technique, where annealed silicon bronze (C65500 alloy) sheets are cut into square shapes, and the center hole is created according to required specifications. The resulting product is then inspected, packed, and shipped as per order quantity.

Q: How does the smooth, uncoated finish benefit the user?

A: A smooth, uncoated bronze finish provides a clean, attractive appearance while eliminating extra coating layers that might degrade in harsh conditions. This finish, combined with natural silicon bronze properties, ensures minimal maintenance and preserves mechanical and electrical performance over time.
