Description
Si:Siは、マトリックス中に一部固溶し、固溶限を超える部分はSi単相あるいはFe、Mnなどと金属間化合物を形成して析出する。これらのSi単相や金属間化合物がマトリックス中に多数分散すると、前記のように、YAGレーザ光の吸収率が高まって、溶接時の溶け込み深さが大きくなり、レーザ溶接性が向上する。Siの好ましい含有量は0.6〜10%の範囲であり、Si含有量が0.6%未満では溶け込み深さが十分ではなく、接合強度が低下するため好ましくない。10%を超えて含有すると、鋳造時にSi単相が100μm以上の晶出物として晶出することがあり、製品板の状態でも15μm以上の析出物として存在することになり、防爆機能を付与する成形加工部にこれらの粗大な析出物が存在すると亀裂発生の起点となる。成形性を考慮したSiのさらに好ましい含有範囲は1.0〜4.0%である。
表1に示す組成を有するアルミニウム合金を半連続鋳造により造塊した。得られた鋳塊を常法に従って均質化処理、熱間圧延、冷間圧延し、厚さ0.8mmの板材を作成した。その後、380℃の温度で最終熱処理を行い、得られた板材を試験材として下記の方法で評価した。評価結果を表2に示す。なお、表1〜2において、本発明の条件を外れたたものには下線を付した。

- 前記アルミニウム合金が、さらに、Fe:0.5%以上2.0%以下を含有することを特徴とする請求項1記載の電池ケース蓋用アルミニウム合金板材。
- 前記アルミニウム合金が、さらに、Mn:0.05%以上0.8%未満を含有することを特徴とする請求項1または2記載の電池ケース蓋用アルミニウム合金板材。
