Makers, engineers, and hobbyists who work on precision mechanisms, electrical contacts, or custom shim stacks need a material that holds its shape under repeated stress without corroding. This phosphor bronze strip is stocked in eight carefully graded thicknesses — from ultra-thin 0.1mm foil to a sturdy 0.8mm plate — so you can match the exact gauge your application requires.\u003c\/p\u003e\n\u003cp\u003eEach piece is cut from phosphor bronze (CuSn alloy with phosphorus deoxidation), a copper-tin alloy known for its spring-like resilience, low friction, and excellent corrosion resistance. Available in three sheet sizes — 100 × 100mm (3.94\" × 3.94\"), 200 × 100mm (7.87\" × 3.94\"), and 300 × 100mm (11.81\" × 3.94\") — with thicknesses spanning 0.1mm (0.004\") to 0.8mm (0.031\"). Pieces are supplied in multi-pack quantities scaled to each thickness so you always have spares on hand.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include custom shim stock for bearing preload adjustment, leaf spring blanks for small mechanisms, electrical contact strips for DIY electronics, and wear-resistant bearing liners in light-duty machinery. Long-tail applications such as phosphor bronze shim sheet for CNC fixtures, thin copper spring strip for model engineering, and precision bronze foil for watchmaking repairs are all well served by this range.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\n\u003cstrong\u003eCompatible with:\u003c\/strong\u003e CNC machining, laser cutting, hand shearing, and standard metalworking tools.
