Testermeter-Mw-i-50 Aluminum Radiator Heatsink for 10A 25A 40A Single Phase SSR RELAY
Features
The heatsink adopts 6063/6061 aerospace-grade aluminum alloy as the base material, a key choice for thermal management: Superior thermal conductivity: 201–210 W/(m·K) (far higher than stainless steel or plastic), enabling rapid transfer of heat generated by SSRs (during on-state conduction or switching) from the SSR’s ceramic substrate to the heatsink body. Lightweight & high structural strength: Density of only 2.7 g/cm³ (1/3 that of steel), reducing overall installation weight (critical for DIN rail or panel-mounted systems); tensile strength ≥270 MPa, resisting deformation even under long-term thermal expansion (avoiding gaps between SSR and heatsink). Corrosion & oxidation resistance: Surface treated with hard anodic oxidation (thickness 8–12 μm), forming a dense Al₂O₃ film that withstands industrial environments (e.g., humidity, weak corrosive gases, oil mist). Passes 48-hour neutral salt spray testing (per GB/T 10125), ensuring no rust or surface peeling for 5+ years of outdoor/harsh indoor use. |
