你看过关否~
翻译一：We are a comprehensive enterprise specialized in the production, processing and sales of titanium materials and nickel materials.

中文：我们是一个综合的专业生产、加工、销售、镍钛物料的材料。

翻译二：Our company is integrated enterprise,which is specialized in manufacturing, processing, and marketing titanium, nickel and Ti\Ti alloy materials.

中文：本公司是集企业,是一家专业生产、加工、销售钛、镍、钛、钛铝合金材料。

我写的 ：We are a comprehensive professional production, processing and sales, nickel titanium materials.
我们是一个综合的专业生产、加工、销售、镍钛物料的材料。

Our company is the collection enterprise, is a specialized production, the processing, the sale titanium, nickel, titanium, titanium alloy material.
本公司是集企业,是一家专业生产、加工、销售钛、镍、钛、钛铝合金材料。
We are a comprehensive enterprise specialized in manufacturing, processing, and marketing titanium, nickel and Ti\Ti alloy materials.

这其实是翻译一的前半部分+翻译二的后半部分

但是我认为这样最舒服
We are a comprehensive enterprise specialized in producing, processing and saling of the nonferrous metal such as titanium materials and nickel materials.

Is this one OK?
