Why Use Copper Alloy for Marine Electronics
1. Conductivity and signal transmission efficiency
Core advantages:
The conductivity of copper alloy (such as brass C36000 conductivity ≈ 28% IACS) is much higher than that of stainless steel (≈ 2.5% IACS), ensuring low loss transmission of electronic signals.
Typical applications:
Ship radar high-frequency connector, 5G communication terminal (requiring 99.98% signal integrity).
2. Salt spray corrosion resistance
Extreme environment adaptation:
Aluminum bronze (C95400) has a lifespan of 3000 hours in salt spray testing, which is more than 5 times that of ordinary carbon steel, avoiding circuit short circuits caused by seawater corrosion.
case
Ship sensor housing, underwater electronic sealing joint.
3. Mechanical strength and vibration resistance
High load stability:
Beryllium bronze (C17200) has a yield strength of ≥ 1100MPa and an elastic modulus of 128GPa, and can withstand ship engine vibration (frequency 10-200Hz) without failure.
Application scenarios:
Spring contacts and precision brackets for gyroscopes in shipborne navigation systems.
4. Thermal management performance
Heat dissipation efficiency:
The thermal conductivity of copper alloys (such as beryllium bronze ≈ 105W/m · K) is 500 times that of plastics, which can quickly dissipate heat from electronic components (such as reducing power module temperature rise by 30%).
Typical design:
Ship frequency converter heat dissipation substrate, LED navigation light thermal conductive frame.
5. Electromagnetic shielding and anti-interference
Signal protection:
The shielding effect of copper alloy on electromagnetic waves (such as white copper B30 ≥ 70dB at 1GHz) effectively isolates electromagnetic interference from ship engines and generators.
Application example:
Radar waveguide components, GPS antenna shielding cover.
