• SHIBUICHI SHEET METAL •Shibuichi sheet metal is a traditional Japanese alloy known for its subtle grey-to-silver tone and exceptional patination potential. Typically composed of 75% copper and 25% silver, this sheet alloy offers a unique blend of warmth and refinement, widely appreciated in both classical and contemporary metalwork. Its soft, muted appearance can be enhanced through traditional niiro patination methods to achieve tones ranging from pale silver-grey to smoky charcoal. • KEY POINTS •[Traditional Japanese copper–silver alloy][Approx. 75% copper / 25% silver][Mild grey patina development][Excellent for chasing and inlay][Crafted from ethically sourced metals] • MORE INFO •Shibuichi (meaning “one-fourth” in Japanese) refers to its classic 1:3 silver-to-copper ratio, though variations exist depending on desired colour outcomes. This alloy offers excellent workability and is particularly well-suited to traditional techniques such as mokume gane, inlay, engraving, and repoussé. When treated with niiro patination, shibuichi produces soft, organic colourations that evolve with handling and wear, making each piece visually distinct. • METAL SPECIFICATIONS •[Approx. Composition: 75% Cu, 25% Ag][Density: ~9.1g/cc][Melting Range: ~780–890°C][Hardness: Soft to medium (work-hardenable)][Patinatable: Yes (niiro patina)][Hallmarked: Not typically hallmarked due to traditional alloy status] • USAGE & APPLICATIONS •Shibuichi is prized by jewellers and metal artists for its tonal subtlety and versatility. It is often used in fine jewellery, Japanese-inspired designs, mokume gane laminates, and mixed-metal artworks. Ideal for projects requiring depth, nuance, and an artisanal finish, shibuichi sheet brings a timeless elegance and a refined, historical aesthetic to any handcrafted piece.
