南铝Hulamin铝业是非洲大陆生产预拉伸板的工厂，可按照AS9100生产AMS标准规范的铝板。但该厂并没有取得各航空制造公司的资格认证。属于纯粹的商用板材供应商。其轧制产品特点如下：
一、优点：

1.成熟的表面拉丝处理工艺，客户认可度高。

2.由于轧机小，宽幅窄，所以平直度和厚度公差都非常好。
二、缺点：

1.由于资质不足，航空工业应用范围受到限制。

2.质量控制细节不足，高等应用稳定性较差。

Industry in the demanding North American market has standardised on the use of aluminium alloy 6061 as its primary plate grade for machining applications.

We designed our M61 plate to meet an exacting blend of exceptional attributes that deliver consistent and excellent machinability. Hulamin’s M61 is a machinable plate that offers gauge and flatness tolerances to tighter than 0.高等A specifications, together with enhanced surface finish and post machining stability.

M61 plate – like its M82 cousin – is:

• Stable

• Consistent

• High surface finish

• Tight tolerance

The result is exceptional machining ……. Performance!
