戴維森表示，我們關(guān)注銅和鋁之間的價(jià)格差。正常情況下，如果銅價(jià)比鋁價(jià)高三倍左右，就可能發(fā)生替代。但是目前已經(jīng)高了四倍。因此從價(jià)格角度來(lái)看，存在替代的風(fēng)險(xiǎn)。當(dāng)然這很復(fù)雜，因?yàn)椴粌H僅是價(jià)格問(wèn)題，還有別的問(wèn)題，比如在某些應(yīng)用中使用替代材料在技術(shù)上是否可行？有時(shí)即使技術(shù)上可行，還有其他原因阻止替代發(fā)生。
鋁可能用于風(fēng)塔、太陽(yáng)能系統(tǒng)里的電纜、電動(dòng)汽車(chē)的充電站，甚至是德國(guó)正在建設(shè)的運(yùn)輸可再生能源的電力走廊。
因此，這一點(diǎn)值得留意。但是就目前而言，我們并沒(méi)有看到從銅大規(guī)模轉(zhuǎn)向其他替代品的空間有多大。如果確實(shí)出現(xiàn)這種情況，那么意義會(huì)很重大。如果1%的年消費(fèi)量被替代，就是25萬(wàn)噸。如果未來(lái)10年里每年都損失這么多消費(fèi)量，確實(shí)會(huì)對(duì)消費(fèi)數(shù)據(jù)造成實(shí)質(zhì)影響。
