Silicon bronze stud bolts are highly valued in demanding industrial applications for their excellent corrosion resistance, strength, and durability. As a leading manufacturer and supplier of silicon bronze stud bolts in India, Vision Alloys offers precision-engineered fastening solutions that are built to handle aggressive environments and long-term exposure to moisture, chemicals, and saltwater.
These stud bolts are made from high-quality Silicon Bronze Grade 651 or 655, a copper-silicon alloy known for its superior mechanical strength and resistance to rust, oxidation, and pitting. The alloy also offers non-magnetic and non-sparking properties, making it especially suitable for marine hardware, flammable environments, and electrical installations. Common industries that rely on silicon bronze fasteners include shipbuilding, wastewater treatment, desalination plants, refineries, and heavy structural engineering.
We manufacture silicon bronze stud bolts in thread sizes ranging from M6 to M48 (¼” to 2”), with options for full thread and double-end thread configurations. Threads are available in UNC, UNF, and metric series, conforming to international standards like ASTM B98, ASME B18.2.1, and DIN 976. Depending on the application, we offer surface finishes such as natural bronze, lightly oiled, or custom-coated as per customer specification.
Vision Alloys supplies both domestic and international markets, supporting orders from small repair jobs to bulk industrial projects. Products are securely packed in bags, boxes, or fumigated wooden crates to ensure safe handling and delivery. As an experienced silicon bronze stud bolt manufacturer and stockist, we serve clients across sectors including oil & gas, marine fabrication, renewable energy, infrastructure, and power generation.
Prices for silicon bronze stud bolts typically range from ₹20 to ₹300 per piece, depending on the size, thread type, and surface finish. With our strict quality checks, quick lead times, and reliable service, Vision Alloys remains a trusted name in the supply of non-corrosive bronze fasteners for industrial applications worldwide.
