Essential details
Specification Number:JS000-1
Product Introduction
Metal substrates are base materials crafted from metals or metal alloys, valued for their excellent thermal conductivity, high mechanical strength, and strong processability. They serve as critical components for thermal management, structural support, and functional carrier applications across industries.
Common types include aluminum, copper, steel, titanium, and specialized alloys like aluminum-magnesium or copper-nickel. Each type caters to distinct needs—aluminum and copper excel at heat dissipation, steel offers robust structural performance, while titanium provides superior corrosion resistance.
Widely used in power electronics (such as insulated metal substrates/IMS), LED heatsinks, automotive components, aerospace structures, and printed circuit boards (PCBs), metal substrates thrive in vibration-prone, heavy-load, or high-heat environments. They can be customized via surface treatments (anodizing, plating, passivation), cutting, drilling, or grooving to meet specific project requirements.
Basic Information
- What is a metal substrate?It is a base material made of metal or metal alloy, designed for applications like electronic packaging, thermal management, structural support, or coating carriers, with high thermal conductivity and mechanical strength.
- What are the common types of metal substrates?Typical types include aluminum (Al), copper (Cu), steel (carbon steel, stainless steel), titanium (Ti), and alloy substrates (e.g., aluminum-magnesium, copper-nickel alloys).
- What are the key characteristics of metal substrates?Core traits include excellent thermal conductivity, high mechanical rigidity, good electrical conductivity (except for insulated metal substrates), and strong processability.
Application Scenarios
- Where are metal substrates widely used?They are applied in power electronics (IMS—Insulated Metal Substrates), automotive components, LED heatsinks, aerospace structures, printed circuit boards (PCBs), and industrial machinery parts.
- Why choose metal substrates instead of ceramic or plastic substrates?Metal substrates offer better thermal dissipation than plastics and higher toughness/impact resistance than ceramics, suitable for vibration-prone or heavy-load environments.
- Can metal substrates be used in high-temperature applications?Yes. Most metal substrates withstand high temperatures (e.g., steel up to 800°C+, titanium up to 600°C), with heat resistance varying by metal type and surface treatment.
Technical Specifications
- What is the typical thermal conductivity range of metal substrates?Aluminum: 200-230 W/(m·K); Copper: 380-400 W/(m·K); Steel: 40-60 W/(m·K); Titanium: 15-20 W/(m·K).
- What thickness and size options are available?Standard thickness: 0.3mm-10mm; Custom thicknesses up to 50mm. Standard sizes: 100×100mm to 500×500mm; Custom sizes available based on processing capacity.
- What surface treatments are available for metal substrates?Common treatments include anodizing, plating (Ni, Au, Sn), painting, passivation, and sandblasting—for corrosion resistance, insulation, or bonding enhancement.
Installation & Usage
- How to assemble metal substrates with other components?Methods include soldering, welding, adhesive bonding, mechanical fastening (screws, bolts), or clamping.
- What precautions should be taken during use?Prevent corrosion (especially for uncoated steel/aluminum); Avoid excessive temperature fluctuations to reduce thermal fatigue; Ensure electrical insulation if used in electronic applications (e.g., with IMS).
- Can metal substrates be customized?Yes. Customizations include material selection, thickness, size, surface treatment, cutting shapes, drilling, and grooving.
Maintenance & Storage
- How to clean metal substrates?Use water + neutral detergent or alcohol; Avoid corrosive cleaners (e.g., strong acids/alkalis); Dry promptly after cleaning to prevent rust.
- How to store metal substrates properly?Store in a dry, well-ventilated environment; Coated/treated substrates should be protected from scratches; Uncoated metal substrates can be oiled to prevent corrosion.
- Do metal substrates have a shelf life?No fixed shelf life if stored properly. Inspect for corrosion, surface damage, or coating peeling before use.
Quality & Reliability
- What tests are used to verify metal substrate quality?Key tests include thermal conductivity measurement, tensile strength test, corrosion resistance test (salt spray test), surface roughness inspection, and dimensional accuracy measurement.
- What factors affect the service life of metal substrates?Corrosion, mechanical wear, high-temperature oxidation, and repeated thermal cycling are the main influencing factors.
- Are metal substrates prone to deformation?They have good rigidity but may deform under excessive pressure, high-temperature heating, or improper processing. Proper installation and use can minimize deformation.
