Type B Different Types of Silicon Bronze Washer | Supplier
Type B Different Types of Silicon Bronze Washer
Eliminate galvanic corrosion, reduce fastener failure, and cut total ownership cost — corrosion‑proof flat washers engineered for marine, electrical, and chemical environments.
⚠️ Why Your Current Washer Choice Is Costing You
Buying the wrong type b flat washer or silicon bronze flat washers leads to field failures, rework, and reputational damage. Here are the top pains our clients brought to us:
Galvanic Corrosion Damage
Using carbon steel washers with stainless or aluminium components accelerates electrolytic corrosion — failure rate up to 18% in marine environments (industry benchmark).
Hidden Total Cost of Ownership
Cheap washers fail in 12–18 months; replacement labor, downtime, and logistics inflate cost by 2.7x vs. premium silicon bronze.
Inconsistent Dimensions & Tolerance
Non‑standard types of metal washers cause assembly issues, stripped threads, and reject rates above 5% in high‑volume production.
High Shipping & Lead Time Risk
Overseas suppliers with 8–12 week lead times and unpredictable freight costs (+35% volatility in 2025) disrupt project schedules.
📌 The bottom line: You need a silicon bronze flat washer that delivers corrosion resistance, exact tolerances, and factory‑direct pricing — without supply chain headaches.
✅ Engineered Solution: Type B Silicon Bronze Washers by Boen Fasteners
Our Type B different types of silicon bronze washer range is designed to solve every pain point above. Each washer is manufactured from high‑grade C65500 / C65100 silicon bronze — offering the perfect balance of strength, conductivity, and corrosion resistance.
Superior Corrosion Resistance
Withstands salt spray, acidic rain, and chemical exposure. Tested to 1,500+ hours in ASTM B117 salt fog — ideal for offshore, shipbuilding, and chemical plants.
Precision Type B Geometry
Flatness tolerance ±0.05mm, concentricity < 0.10mm. Conforms to DIN 125 / ISO 7089 / ASME B18.22.1 — compatible with different types of metal nuts and bolts.
Non‑Spark & Electrical Conductivity
Silicon bronze is non‑sparking (safe for explosive atmospheres) and offers ~12% IACS conductivity — perfect for grounding, switchgear, and mining equipment.
Factory‑Direct Cost & Speed
Eliminate middlemen. 30% lower cost vs. imported distributors, and 10–15 day standard lead time (rush orders: 5–7 days).

❓ Frequently Asked Questions
Type A washers have a larger OD and thicker section for general purpose load distribution. Type B washers (like our silicon bronze range) are narrower and thinner, designed for precise fit under different types of metal nuts and in limited clearance applications. Both conform to ASME B18.22.1.
Absolutely. Silicon bronze flat washers offer excellent resistance to chloride corrosion and are widely used in shipbuilding, desalination plants, and offshore platforms. They outperform brass and even some stainless grades in salt fog tests.
Yes. We offer OEM/ODM custom sizes from M3 to M48, with special ID/OD/thickness. Minimum order quantity is 500 pcs for custom dimensions. Provide drawing or sample, and we deliver within 10–15 days.
Standard sizes (M6–M24) in stock: 3–5 days. Production orders (M4–M36): 10–15 working days. Rush orders possible with express service.
Yes. We combine silicon bronze, brass, copper, stainless steel, and galvanized washers in one container. You also can add different types of metal nuts and bolts to the same shipment — saving freight cost.
