C44300 and H62 copper tubes differ significantly in several aspects. Below is a detailed comparison of the two types:
Chemical Composition
C44300 copper tubes:
Mainly composed of copper (Cu), zinc (Zn), tin (Sn), and trace amounts of arsenic (As).
The copper content is approximately 69.0% to 71.0%, with zinc as the remainder. The tin content ranges from 0.8% to 1.3%, and the arsenic content is trace, typically around 0.03% to 0.06%.
H62 copper tubes:
Mainly composed of copper (Cu) and zinc (Zn).
The copper content ranges from 60.5% to 63.5%, with the remainder being zinc.
It also contains small amounts of impurity elements, such as lead (Pb) not exceeding 0.08%, iron (Fe) not exceeding 0.15%, and other impurity elements such as boron (P), beryllium (Sb), and bismuth (Bi). The contents are strictly controlled.
Performance Characteristics
C44300 Copper Tube:
High Corrosion Resistance: Demonstrates high corrosion resistance in a variety of environments, including air, steam, oil, and seawater, with particularly excellent resistance to seawater corrosion.
Good Mechanical Properties: Excellent tensile strength and elongation.
Easy Processing: Excellent hot and cold press working properties, and easy welding and lead soldering.
H62 Copper Tube:
Good Mechanical Properties: Excellent hot plasticity and acceptable cold plasticity.
Good Machinability: Excellent surface quality and processing efficiency are achieved in turning, milling, and drilling.
Easy Welding: Convenient for connection and assembly.
Fair Corrosion Resistance: Under certain conditions, such as water or air containing corrosive media, corrosion cracking can occur.
Applications
C44300 Copper Tube:
Commonly used for corrosion-resistant parts on ocean-going vessels, such as condenser pipes.
Conduits in contact with seawater, steam, and oil.
Parts of thermal equipment.
H62 Copper Tube:
Electronic and electrical applications: Used in the manufacture of various connectors, terminals, lead frames, etc.
Plumbing and sanitary ware: Used in the manufacture of faucets, valves, and pipe fittings.
Mechanical and structural parts: Fasteners such as pins, rivets, washers, and nuts, as well as auxiliary equipment such as conduits, pressure gauge springs, and screens.
Price and Cost
C44300 Copper Tube: Due to its high corrosion resistance and the presence of tin and trace amounts of arsenic, it is relatively expensive.
H62 Copper Tube: Relatively affordable and a widely used common brass variety.

Packaging and shipping
GNEE offers professional packaging for exported copper pipes. First, we apply anti-rust oil and plastic film to prevent oxidation. Then, we securely strap with steel straps and add corner protectors. Finally, we place the pipes on wooden pallets and reinforce them with iron or wooden boxes, ensuring they are moisture-proof and impact-resistant during ocean transport, while facilitating easy loading and unloading. All packaging meets export standards.
