With high current connections it would be wise to use real copper to ensure best connection and conductivity. All 4Connect terminals that are for 20 mmq or larger cables, are made of 100% copper. Connectors are rhodium plated to secure connection for years. This package includes 10pcs black connectors that fit to M6 bolt and take 20 mm2 cable.
