All copper terminal refers to the wiring terminals installed on the power amplifier and speaker for connecting with the speaker wire, and its material is mainly copper and brass. Copper, that is, pure copper, its copper content reaches
99.9%, while brass is alloy copper, composed of about 60% copper and about 40% zinc, individual grades may contain about 1% lead, so brass is impurities. Regular manufacturers usually choose national standard copper H59 or H62 copper, which means that the copper content is about 59% and 62%, respectively. The price of copper is much higher than brass.
The plating of all copper terminals includes rhodium plating, gold plating, silver plating, chromium plating, nickel plating, etc. Among them, silver has the best electrical conductivity, but it is easy to oxidize and not wear-resistant; Gold has better antioxidant capacity, but the electrical conductivity is not as good as silver and copper; Rhodium is a compromise choice of both conductivity and antioxidant; Chrome, on the other hand, is not as conductive as those three, but is hard and durable. These plating processes typically start with a red copper base, then nickel, and finally a corresponding coating.
From a cost perspective, the actual all-copper gold-plated terminal refers to a combination of all-gold plated screw + nut and screw, while the all-copper chrome-plated terminal is a combination of all-chrome plated screw + nickel-plated nut + nickel-plated screw. The choice of these materials and processes has an important impact on both the performance and appearance of the all-copper binding post .
