一， 管材Tube Material

目前，用于氮气保护气体钎焊的管料主要分三类：

At present, there are three kinds of tube material for CAB.

a） 普通常用的AA3003系列合金，具有较好的强度和抗腐蚀性能。

General AA3003 series alloy, which has enough strength and corrosion

resistance properties.

b） “长寿命”合金，具有较高的强度和优良的抗腐蚀性能。

Long life alloy, which has high strength and good corrosion resistance

properties.

c） 最新开发的合金，具有更高的强度和优秀的抗腐蚀性能。

Up to date new developed alloy, which has excellent strength and corro-sion resistance properties.

管料的发展方向是不断提高管材的机械性能满足材料减薄的要求，同时提高抗腐蚀性能,提高使用寿命，降低成本。

The trend is to improve the mechanical properties of the tube material to

meet the requirement of down gauging, improve the corrosion resistance

properties and the service life, and also cost saving.

SAPA向贵司推荐上述三类氮气保护气氛钎焊管材，并将其进行对比分析，供贵司参考选择。

SAPA recommend the above mentioned CAB tube materials for your

choice, and we make the comparison list for your reference.

The two fin stock have been in your mass production. The process of

CC FA6811 is a little different, but the final mechanical properties is a little

better.

3， 主板材料 Plate Stock

a) FA82A4

b) FA8ED4

c) FA8ET4

d) FA8UA4

推荐的三种主板材料(a,b,c)，经过客户批量使用，已经得到了验证。对于FA8UA4材质的主板材料，目前是我公司开发的新合金材料.

The three plate stock have been also in your mass production. But the

alloy FA8UA4 is a new alloy for header plate.

4， 材料的匹配The Match

上述主板，管材和翅片材料通过组合能够相互匹配，最终能够满足产品加工工艺和各类性能要求，包括机械和腐蚀性能的要求。

The recommended materials could be matched properly to meet the

process ,mechanical and anti-corrosion requirement.
