Title: Tube material for heat exchanger
Inventor: YAMAGUCHI MOTOYOSHI
IPC: F28F19/06
Filed: 1989-05-18
Abstract: PURPOSE:To improve corrosion resistance of a heat exchanger and to remarkably improve its life by covering the surface of an extruded tube material of Al or Al alloy with Al containing specific amount of Sn or In or Al-Zn alloy. CONSTITUTION:The surface of an extruded tube material of Al or Al alloy is coated with Al containing totally 0.05-3wt.% of one or both of Sn and In or Al-Zn alloy. This is because the Sn and the In are potentially base element and not evaporated even if it is brazed to be heated at 600 deg.C in N2 gas in vacuum. In the tube material coated with such Al alloy, etc., the coating layer becomes a sacrificing layer to have through hole corrosion preventive effect of the material. If the total content amount of the Sn and the In is less than 0.05%, the potential is not sufficient at its potential to the tube material, and corrosion resistance effect cannot be obtained. If it exceeds 3%, the effect is not only saturated, but self-corrosion resistance is deteriorated. The coating includes, for example, a flame spraying method, and its coating amount is desirably 5-100g/m<2>.
