The Harris Stay-Silv 15 is a premium phos-copper-silver brazing filler metal designed for high-integrity joints in copper and brass systems. Formulated with a composition of 15% Silver, 5% Phosphorus, and a Copper balance, this alloy meets the AWS A5.8 BCuP-5 classification. It is specifically engineered for applications requiring high ductility and resistance to vibration, making it the preferred choice for HVAC and refrigeration service technicians and fabricators.<\/p>\n
One of the defining characteristics of Stay-Silv 15 is its wide melting range (Solidus 1190\u00b0F \/ Liquidus 1480\u00b0F). This property allows the alloy to transition slowly from solid to liquid, providing a “plastic” range that is excellent for filling loose connections or bridging gaps where close fit-up cannot be maintained. While it is self-fluxing on copper-to-copper joints due to its phosphorus content, the use of Stay-Silv\u00ae white or black flux is required when brazing brass or bronze fittings.<\/p>\n
This product is supplied in a protective tube containing 24 rods, each with a diameter of 2.5mm. The 15% silver content significantly lowers the liquidus temperature compared to BCuP-2 or BCuP-3 alloys, improving flow characteristics and reducing the heat input required, which minimizes grain growth in the base metal. Note: This alloy should not be used on ferrous metals or nickel alloys, as the phosphorus can form brittle intermetallic compounds leading to joint failure.<\/p>\n","protected":false},"excerpt":{"rendered":"3\/32″ dia x 20″ (2.38 mm dia x 508 mm) – 24 Stick Tube.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1966,1959],"product_tag":[],"class_list":["post-1761512","product","type-product","status-publish","product_cat-silver-wires","product_cat-welding-wires-and-electrodes","pa_diameter-mm-2-5mm","pa_packaging-description-1-per-each","pa_packaging-description-24-rods-in-a-pack-2","pa_silver-content-1541","pa_silver-content-1315","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
