Bill Fretz developed these after repeated requests from working jewelers — each form arrives pre-cut, edge-finished, annealed, and tumbled so you can move directly into your forming process without additional prep.\u003c\/p\u003e\n\n\u003cp\u003eFretz uses seamless extruded tubing made from a malleable brass alloy of 70% copper and 30% zinc. The tubing is cut to size, edges are cleaned on a belt sander, then each piece is annealed and given a basic tumbled finish. The seamless construction ensures consistent wall integrity throughout the form.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eKeep in mind: when making convex (domed) forms, doming will reduce the finished diameter of the piece. When making concave forms, the finished diameter will not be affected.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSeamless extruded brass construction for consistent wall integrity\u003c\/li\u003e\n\u003cli\u003eMade from a malleable 70% copper \/ 30% zinc brass alloy\u003c\/li\u003e\n\u003cli\u003e20 gauge (0.81 mm) wall thickness\u003c\/li\u003e\n\u003cli\u003eEdges cleaned on a belt sander for smooth, ready-to-use blanks\u003c\/li\u003e\n\u003cli\u003ePre-annealed for immediate forming and shaping\u003c\/li\u003e\n\u003cli\u003eBasic tumbled finish applied before packaging\u003c\/li\u003e\n\u003cli\u003eDesigned by Bill Fretz in response to professional jeweler demand\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDiameter\u003c\/th\u003e\n\u003ctd\u003e1 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e3\/8 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWall Thickness\u003c\/th\u003e\n\u003ctd\u003e20 gauge (0.81 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eBrass — 70% copper, 30% zinc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eSeamless extruded tubing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eAnnealed, tumbled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePack Quantity\u003c\/th\u003e\n\u003ctd\u003e3 pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e3 brass tube forms, 1 in. diameter × 3\/8 in. wide\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fretz","offers":[{"title":"Default Title","offer_id":43583715999958,"sku":"143.340","price":7.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/fretz-bt-10-brass-tube-forms-1-x-38-pack-of-3-otto-frei-1.jpg?v=1719956529","url":"https:\/\/www.ottofrei.com\/it\/products\/fretz-bt-10-brass-tube-forms-1in-x-3-8in-pack-of-3","provider":"Otto Frei","version":"1.0","type":"link"}
