Shim stock for bearing preload or machine alignment usually falls in the 0.1 mm–0.5 mm range. Structural tooling inserts or wear plates generally use 0.8 mm–2.0 mm.

Standard copper (C110) has a tensile strength of roughly 220–250 MPa. Beryllium copper in the age-hardened condition typically reaches 1,000–1,400 MPa, making it one of the strongest copper alloys available. This spring-like strength is why BeCu is chosen for contacts and precision springs that must return to shape after repeated deflection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill these sheets corrode or tarnish in humid environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eBeryllium copper has good resistance to oxidation and stress-corrosion cracking compared to standard copper alloys. In most indoor and light industrial environments, surface tarnish is minimal.

In the annealed (soft) state, BeCu sheet can be sheared with standard metal shears, punched, CNC laser-cut, waterjet-cut, and bent on a press brake. After forming, the part can be age-hardened in an oven to achieve full spring temper. Always follow appropriate safety precautions when machining beryllium-containing alloys — use wet cutting methods and proper ventilation to control fine particulate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these sheets compatible with soldering and brazing?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. Beryllium copper can be soldered using standard tin-lead or lead-free solders with appropriate flux. Silver brazing is also compatible. Spot welding and resistance welding are possible with proper electrode selection. Avoid prolonged high-temperature exposure that could over-age the alloy and reduce hardness.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat size should I order if I need a custom shape?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eChoose the sheet size that is closest to — but larger than — your finished part dimensions to minimize waste. The 200×200 mm sheet suits small contacts and shims. The 200×500 mm and 200×1000 mm sheets are better for longer strips, spring blanks, or multiple smaller parts nested together. The 200×215 mm option is available in select thicknesses for near-square blanks.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I decide between 1.0 mm and 1.2 mm thickness for a tooling shim?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eIf your gap measurement falls between the two, choose the thicker option and lap or grind to final dimension — BeCu machines cleanly.
