AUTIUM NOBLE SILVER SERIES
Silver is prone to sulphur, a persistent presence in the atmosphere. Silver jewellery and articles produce black-coloured silver sulphide – more commonly referred to as tarnish – when exposed to sulphur. Taking care of the metal can be a hassle especially in modern cities where sulphur content is high among the air.
Autium Materials’ Noble Silver Series is a range of master alloys that protects silver from tarnishing right from when it is manufactured. Ascertained by ISO standard test, Autium Noble Silver is at least 222% more tarnish resistant than regular silver alloys among the market. This superior anti-tarnish quality is obtained by a tri-function secret formula that scavenges oxide, prevents formation of silver sulphide and builds a cover layer when the alloy is mixed.
Additionally, Noble Silver creates natural products that exhibit lasting, lustrous colour comparable to white gold. This saves you from the additional time, effort and cost to plate the silver. In fact, Noble Silver is safe and easy to manufacture with remarkable versatility (compatible for 80-97% silver purity), excellent workability (suitable for cast, sheets and wire-drawing), great tolerance for annealing, as well as being fire-scale or firestain proof.
Noble Silver is also 100% nickel free and compliant to RoHS requirement.
