铝复合材、热交换器及助焊剂
摘要：
一种铝复合材，其具备含有镁的铝合金材、和通过使用助焊剂的钎焊而形成并将上述铝合金材接合的接合材。铝复合材中，上述接合材含有KMgF3和MgF2以外的含镁化合物。本发明提供对含有镁的铝合金材实施了良好的钎焊的铝复合材和具备该铝复合材的热交换器、以及能够适用于所述钎焊的助焊剂。
摘要（英）：

Disclosed is an aluminum composite material including an aluminum alloy material containing magnesium, and a bonding material formed by brazing using a flux, the bonding material being adapted to bond the aluminum alloy material thereto. In the aluminum composite material, the bonding material contains a magnesium-containing compound other than KMgF3 and MgF2. The present invention provides an aluminum composite material with satisfactory brazeability to an aluminum alloy material containing magnesium, a heat exchanger including the aluminum composite material, and a flux suitable for use in braze.
