Brass is an alloy of copper and zinc, also known as brass. The five yen coin is also brass.

Equivalent to faucets, nuts, Buddhist tools, wind instruments, etc.

Dust should be removed from things with dust.

Some people also write "Zhen Zhong" or "Zhen Zhu".

The wire cutting of brass also belongs here, but the cut should be reduced.

Pay attention to the mixing of stainless steel around the tap.

It is common to use zinc instead of brass around the valve and plug of gas and tap water, so attention should be paid. Zinc also appears yellow, please confirm carefully.

The gold-plated objects around the tap include brass, cannon gold, and rare copper, but due to their inseparable nature, they are used as brass.

Due to the presence of impurities and oil adhering to the brass powder, it is significantly reduced (even without impurities and oil, it cannot be fully investigated, so it has to be done).

The unit price of brass coins varies, and if mixed together, there may be situations where they cannot be purchased.
