6AL-4V GR5鈦合金是大多數(shù)行業(yè)中最常用的合金。6AL-4V GR5鈦合金強(qiáng)度比商業(yè)純鈦高，但仍具有相同的剛度和大部分相同的熱性能。6AL-4V GR5鈦合金的最重要特征之一是它可以熱處理，甚至可以焊接。無論您是在航空航天，汽車還是其他行業(yè)，這種合金都可以用于廣泛的應(yīng)用中。下圖顯示了這種6AL-4V GR5鈦合金的機(jī)械、拉伸和物理性能。我們的一些可用的產(chǎn)品包括6AL-4V / 5級鈦合金棒，管，絲材以及定制產(chǎn)品。如果您想了解更多有關(guān)選擇的信息，請立即聯(lián)系我們以了解更多信息。
