How to deal with the problem of copper rust

All copper or copper alloy will rust in the natural environment, but the degree is different, which is slower to rust without oxygen copper, followed by most bronze and ordinary industrial pure copper (industrial copper) brass is easier to rust, especially with H59 the most easy to rust, which is decided by the characteristics of its chemical composition.

H59 brass is easy to rust, but as a machine part, there is a requirement, H59 brass has many advantages: wide sources, low cost, easy cutting (processing), strength higher than that of pure copper, while it is easy to rust shortcomings, but is still a brass, they are widely used in manufacturing by plating (nickel) can have a better appearance, and effectively improve the corrosion resistance, rust ) performance. Other copper and copper alloys, due to their high cost, low source, and poor cutting performance, are not generally used in place of H59 brass.

Two, copper rust removal method

1, grinding method

With the common toothpaste toothbrush at home gently wipe copper rust, clean with clean water, like brushing teeth, of course, also useful ash or eraser hard in copper rust parts can also wipe rust.

2, vinegar bubble method

The copper to be cleaned, the copper into a suitable container, pour a little vinegar, until soaked, soaked out, and then small brush to brush the rust, and then rinse vinegar, wipe dry.

3. Soak in boiling water

Rusty copper sometimes covered with a layer of soil rust can not wash off, then can be put into the bowl of rusty copper, and then poured into the temperature of 80 degrees to 90 degrees of boiling water, until the immersion,5 minutes after it is removed, with a small brush brush, dry, encountered serious soil rust, can also heat the water to boiling, so that the soil rust off.

4, chemical rust removal method

You can buy derusting water or derusting cream, the effect is also very good, of course, the first step must be in the derusting place rub a little sesame oil to do a protection
