Physical and chemical properties of brass coils:

Physical properties:

1. Appearance: Usually yellow.

2. Density: generally between 8.39 and 8.53 g/cm ³.

3. Melting point: The liquid phase melting point is about 900 to 955 ° C, and the solid phase melting point is about 900 to 915 ° C.

4. Coefficient of thermal expansion: about 10-6/19 to 20.8.

5. Thermal conductivity: approximately 0.29 cal/cm ²/cm/sec.

6. It has a certain degree of ductility and can be changed by machining.

Chemical properties:

1. Corrosion resistance: It generally has good corrosion resistance in the atmosphere, fresh water, and seawater.

2. Brass is easily oxidized at high temperatures, forming an oxide film on the surface.

3. It can react with some acids, but the reaction rate is relatively slow.

4. Brass is a copper-zinc alloy, and the stability of its composition ratio affects the stability of its chemical properties to a certain extent.

Stringent product quality inspection

Surface quality inspection
Use the surface roughness detector to inspect the surface roughness, the adhesion and thickness of the coating (if any).
Appearance inspection
Check whether there are scratches, pits, rust spots, oxide skin and other defects on the surface of steel products.
tensile test
Determine indicators such as tensile strength, yield strength, elongation, etc., and evaluate the strength and plasticity of the steel plate.
Galvanized layer inspection
Make sure that the thickness of the galvanized layer meets the specified requirements to provide adequate corrosion protection.
Size detection
Measure the diameter, length, and thickness of steel pipes to ensure they meet specific customer requirements.
Spectral Analysis
Examining Steel Composition Through Emission Spectra Using Advanced Spectroscopic Methods and Techniques
Bending detection
Observe whether there are cracks, folds, peeling and other defects on the surface of the bent steel plate.
non-destructive testing
Used to detect internal defects in steel, such as cracks, pores, etc.

Inventory and Package

Plate package

steel plates together using steel bands and then wrapped in waterproof paper or plastic sheets to protect against moisture and corrosion

Coil package

Steel coils are wrapped in waterproof paper or plastic sheeting and sometimes further protected with metal sheet covers.

Pipe package

Pipes are usually bundled together and strapped. Ends are often capped to prevent damage and ingress of dirt,anti-corrosion measures.

Rod package

The bundles are then wrapped with waterproof material, and sometimes, anti-rust oil or coatings to prevent corrosion.
