FAQs

1. What is the difference between copper and brass?

Copper is a pure metal, while brass is an alloy of copper and zinc. Brass is typically stronger and more durable than copper, but it is also less conductive.

2. What are the different types of brass?

There are many different types of brass, each with its own unique properties. Some of the most common types of brass include:

• 黃銅：Yellow brass is the most common type of brass. It is made from 65% copper and 35% zinc.
• 紅銅：Red brass is made from 85% copper and 15% zinc. It is stronger and more corrosion-resistant than yellow brass, but it is also less ductile.
• 海軍黃銅：Naval brass is made from 60% copper, 39% zinc, and 1% tin. It is strong, corrosion-resistant, and ductile.
• 鋁黃銅：Aluminum brass is made from 76% copper, 22% zinc, and 2% aluminum. It is strong, corrosion-resistant, and ductile.

3. How is brass made?

Brass is made by melting copper and zinc together in a furnace. The proportions of copper and zinc can be varied to create different types of brass with different properties.

4. What are the advantages of using brass?

Brass is a versatile and durable material with a number of advantages, including:

• 強度和耐用性：Brass is strong and durable, making it ideal for use in a variety of applications.
• 延展性和可鍛性：Brass is malleable and ductile, making it easy to shape and form.
