QSn8.0-0.3（C5210）銅合金品質(zhì)保證

高品質(zhì)紅銅純度高，組織細(xì)密，含氧量很低。無氣孔、沙眼、疏松，導(dǎo)電性能很好，適合電蝕刻模具，經(jīng)熱處理工藝，電很無方向性，適合精打，細(xì)打。

參考參數(shù)：Cu≥99.95%O<003電導(dǎo)率≥57ms/m硬度≥85.2HV

column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor

differences. The column in the middle states the norm and its country of origin.

With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.

銅合金的分類方法有三種：

按合金

按合金系劃分，可分為非合金銅和合金銅.非合金銅包括高純銅、韌銅、脫氧銅、無氧銅等，習(xí)慣上，人們將非合金銅稱為紫銅或純銅，也叫紅銅，而其他銅合金則屬于合金銅。我國和俄羅斯把合金銅分為黃銅、青銅和白銅，然后在大類中劃分小的合金系。
