What is Brass
Brass is a metallic alloy derived from combining copper and zinc. Known for its bright gold-like appearance, brass is both malleable and durable. As a result, it can used for a variety of purposes, from musical instruments to decorative items. Its corrosion resistance & aesthetic appeal place it in both functional and artistic realms.
Material Composition of Brass
Brass is an alloy consisting of two elements:
Copper (Cu):
The major component of brass, copper usually forms anywhere from 55% to 90% of the alloy. Depending on the desired properties and applications.
Zinc (Zn):
Zinc is the secondary element, making up the remaining percentage of the alloy. Influencing the alloy’s strength, ductility, and color.
Advantages of Using Brass
Corrosion Resistance:
Brass has excellent corrosion resistance, specific to moisture and salt water. This makes it perfect for plumbing and marine applications.
Malleability:
Brass is very flexible, making it easy to shape and form. This property is beneficial in the manufacture of intricate components and decorative items.
Low Friction:
The alloy has low friction. Which is important for applications such as locks, gears, and doorknobs.
Heat Conductivity:
Brass conducts heat well. Making it suitable for hot water supply systems and heat exchangers.
Aesthetics:
Brass’s bright gold-like appearance is attractive to the eye. Leading to its use in decorative fixtures, jewelry, and architectural elements.
Recyclability:
Like other metals, brass is recyclable, allowing for sustainability in its usage.

How to Tell if The Material is Brass
This quick reference offers crucial advice to assist you in determining whether a material is brass. A skill that comes in handy for a variety of tasks and applications. Here’s how you can identify brass:
Color:
Brass has a distinct bright gold-like hue, like a gold coin. Yet, the precise shade will depend on the amount of zinc present. Higher zinc content tends to make brass appear more yellowish.
Magnet Test:
Brass is not magnetic. You could use a magnet to attach the object. If it doesn’t stick, it might be brass.
Weight:
Brass items are heavy for their size, owing to the density of the metal.
Scratch Test:
Carefully scratch an inconspicuous area of the item with a sharp object. Brass will reveal a bright yellow color beneath the surface.
File test:
Scratch a small area of the object with a file. If the material is brass, it will have a gold-like color underneath.
Examine for Patina:
Over time, brass develops a patina—a greenish or brownish layer. This tarnish can be a sign of brass, especially on older items.
Smell Test:
Sometimes, brass has a distinct metallic smell. Rubbing the item may cause the odor to become more noticeable.
Use of Chemicals:
Often contain acids that can be applied to metals to test their composition. The reaction (or lack of reaction) can help determine if the material is brass.
Remember, while these tests can be effective, they may not be 100% conclusive. Always be cautious when conducting tests that may damage or devalue an item.

What is Stainless Steel
Stainless steel is an alloy of iron, chromium, nickel, and other metals. This material is strong, has an appealing appearance, and has exceptional corrosion resistance, making it perfect for industrial and consumer industries.
Material Composition of Stainless Steel
Iron (Fe):
The primary base metal of stainless steel, makes up the majority of its weight.
Chromium (Cr):
Usually found in concentrations between 10.5% and 30%. By creating a passive oxide layer on the alloy’s surface. Chromium manages the alloy’s corrosion resistance, which protects the underlying metal.
Nickel (Ni):
Added to increase the alloy’s ductility, formability, and resistance to corrosion.
Carbon (C):
Present in small amounts of carbon. It may affect the steel’s hardness and tensile strength. Yet too much carbon can reduce the alloy’s corrosion resistance.
Molybdenum (Mo) & Tungsten (W):
Added to some stainless steel grades. To further improve corrosion resistance, especially in more aggressive environments.
Silicon (Si) & Manganese (Mn):
Added to aid in manufacturing. To enhance the alloy’s resistance to oxidation.
Nitrogen (N):
Used as a strengthening element in certain stainless steel varieties.
Depending on the desired properties & particular grade, stainless steel’s precise composition can change. This adaptability in composition results in a wide range of stainless steel types. Such as 304, 316, or 410, each designed for different applications and environments.

Galvanized Steel:
Steel is coated with a layer of zinc to resist corrosion.
Difference Between Brass and Stainless Steel
Brass versus stainless steel, both materials have different compositions, appearances, and physical characteristics. Brass is a copper-zinc alloy known for its bright gold-like hue. Stainless steel is an iron-chromium alloy prized for its corrosion resistance. Let’s explore the difference between brass and stainless steel:
Brass vs. Stainless Steel: Strength
Brass: Its strength depends on the zinc content. Higher zinc means greater strength but decreased ductility. Generally, brass has moderate tensile strength.
Density; 8.49 g/cc
Tensile Strength; 338 – 469 MPa
Tensile Strength; 124 – 310 MPa
Stainless Steel: It generally possesses higher tensile strength compared to brass. Especially certain grades designed for strength.
tensile strength of 621 MPa (90 ksi)
Brass vs. Stainless Steel: Durability
Brass: Brass is durable and resistant to corrosion. Especially when alloyed with elements like tin. But it can tarnish or develop a patina over time.
Stainless Steel: Stainless Steel:
It has an outstanding reputation for toughness and resistance. due to the presence of chromium, and rust. It resists tarnishing and corroding well, even when exposed to moisture and water.
Brass vs. Stainless Steel: Price
Brass rmb/ton
60000 = $60500
63000 = $63500
62000 = $62500
62000 = $62500
Stainless Steel rmb/ton
304/No.1 = 14050 – 14150 = $14100
