Based in the industrial heart of Hamilton, New Zealand, Will Sheetsandplates has built a strong reputation for supplying top-tier materials to a wide range of demanding industries. We take particular pride in our expertise with Alloy 20 sheets and plates, a high-performance alloy known for its exceptional durability. Our team understands that reliable materials are the foundation of any successful project, which is why we ensure every sheet and plate we supply meets the highest standards of quality and consistency, backed by our local knowledge and commitment to customer service.
The strength of Alloy 20 lies in its thoughtful composition, primarily a nickel-iron-chromium alloy enriched with significant copper and molybdenum. This specific blend grants it outstanding resistance to corrosive substances, particularly sulfuric acid, and provides excellent protection against stress corrosion cracking. Mechanically, it is a robust material that offers good strength and ease of fabrication, including welding and forming, making it a practical and long-lasting choice for engineers and fabricators who need a material that can handle tough conditions without faltering.
