Melting Point of Brass and Brass Alloy Specs

Melting point of brass explained with brass alloy specs thermal properties and precisionvast industrial brass products for casting and machining.

Brass Melting Temperature and Technical Specs

When you are casting, forging, or machining, knowing the exact melting point of brass is critical. Push the heat too far, and you ruin the batch. Run it too cold, and your molds won’t fill. We engineer our copper-zinc alloy specifications to give you predictable, repeatable results on the factory floor.

The secret lies in the material composition. Brass is primarily a mix of Copper (Cu) and Zinc (Zn). The exact ratio dictates how the metal behaves under extreme heat. Higher zinc content lowers the melting point, while higher copper content drives it up.

Thermal Properties of Brass

Here is the exact breakdown of how our industrial brass materials handle heat.

Brass Grade	Melting Point (°C)	Melting Point (°F)	Thermal Conductivity (W/m·K)	Coefficient of Thermal Expansion
Yellow Brass	905°C – 932°C	1660°F – 1710°F	116	20.5 µm/m·°C
Red Brass	990°C – 1025°C	1810°F – 1880°F	159	18.7 µm/m·°C

Frequently Asked Questions About the Melting Point of Brass

Understanding the thermal limits of copper-zinc alloys is essential for successful fabrication and long-term part performance. Here are the most common questions we address regarding the melting point of brass and its behavior under heat.

What is the exact melting point of brass?

There is no single “exact” number because brass is an alloy, not a pure metal. The melting point of brass typically falls within a range of 1,650°F to 1,725°F (900°C to 940°C). The specific temperature depends entirely on the ratio of copper to zinc and the presence of other elements like lead or tin.

How does the zinc content affect the melting temperature of brass?

Zinc has a much lower melting point than copper. Consequently, as you increase the zinc content in the alloy, the overall melting temperature of the brass decreases.

• High Zinc Content: Lowers the melting point, making the metal easier to cast but potentially more brittle.
• Low Zinc Content: Raises the melting point, closer to that of pure copper (1,984°F).

Can brass withstand high-temperature applications without deforming?

Brass maintains its structural integrity well at moderately high temperatures, but it begins to soften long before it reaches its melting point. For applications involving extreme heat, we monitor the “solidus” temperature—the point where the alloy starts to lose its rigid state. If your project involves pouring molten metal, understanding aluminum shrinkage during casting can provide a helpful comparison for how different alloys behave as they cool and solidify.

What is the difference in melting points between red brass and yellow brass?

The primary difference lies in the copper concentration.

• Red Brass (C230): Contains about 85% copper. It has a higher melting point, usually around 1,880°F (1,027°C).
• Yellow Brass (C260/C360): Contains more zinc (approx. 30-40%). It has a lower melting point, typically between 1,650°F and 1,725°F.

For those involved in foundry work, mastering the aluminum sand casting process offers great insight into how temperature control and mold design are critical when working with various non-ferrous alloys like brass.
