In this guide, you&#8217;ll learn about the materials they&#8217;re constructed of, how their properties fluctuate by common grade, where they fit on the factory floor, and what you should inspect before you place a purchase order.<\/p>\n<p><b>Key Takeaways<\/b><\/p>\n<ul>\n  <li>BeCu Sheets are made by adding a small amount of Be (usually 0.5 to 3 per cent) to Cu to achieve a tensile strength greater than 1,300 MPa without sacrificing the electrical conductivity of the Cu base material.<\/li>\n  <li>The two most frequently requested grades are C17200 (for maximum strength) and C17500 (for higher conductivity); the choice depends on whether the part carries current or absorbs stress.<\/li>\n  <li>The applications include aerospace fasteners, non-sparking tools for oil &#038; gas, electrical connectors, and injection mold parts.<\/li>\n  <li>Thickness, temper, and surface finish all affect lead time and cost, so check with your supplier before placing an order.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Beryllium-Copper-Sheets-Properties-That-Actually-Matter-for-Design-Work\"><\/span>Beryllium Copper Sheets Properties That Actually Matter for Design Work<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n  <li><b>Strength and hardness<\/b>. As for temper, the tensile strength of sheet C17200 can be approximately 1,380 to 1,400 MPa (200 ksi) when age-hardened, and the Rockwell C hardness is 34-45, closer to some tool steels than ordinary copper alloys.<\/li>\n  <li><b>Conductivity<\/b>. Peak-aged C17200 has an IACS of about 22 percent, which is relatively low compared to pure copper but higher than typical for an alloy of this strength. The same applies to thermal conductivity, which is why mold makers use it for faster cooling cycles.<\/li>\n  <li><b>Fatigue, corrosion, and safety behaviours<\/b>. These sheets will not crack through repeated flexing, will last long in most industrial environments, and won&#8217;t ignite on impact, making them recommended for tools around flammable gases.
