  材料特性 Material Characteristics

  商业纯锻造镍（99.6%）,和Nickel 200具有相同的镍含量。但是相对较低的碳含量可以阻止在超过600°F（315℃）高温下因晶间碳导致的脆变；较低的碳含量还可以减少硬度，这一点使Nickel 201特别适合冷成型产品。

  Commercial pure wrought nickel (99.6%)has the same nickel content as Nickel 200. However, but a relatively low carbon content can prevent embrittlement due to intergranular carbon at temperatures above 600 ° F (315 ℃); lower carbon content also reduce hardness, which makes Nickel201 particularly suitable for cold formed products.
