BAg-6, Braze 501, Braze 502, Braze 503, Silvaloy A50, Silver Braze 50. For steam turbine blades. For thickly galvanized steel, aluminium and brass tubing. Widely used in electrical industry. Used in dairy industry. Broad melting range, can form fillets and bridge large gaps. 34: 16: 50: Ag 50 Cu 17 Zn 33: Ag–Cu–Zn 780/870 [41] –
Extended heat treatment leads to formation of crystals of binary alloys. Silver content decreases solubility of silver, making the alloy suitable for soldering silver-metallized surfaces, e.g. SMD capacitors and other silver-metallized ceramics. [55] [56] [13] Not recommended for gold. [12] General-purpose. Sn 61 Pb 36 Ag 3: 205 [62] Pb
Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder. It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [ 1 ] as it is near eutectic , with adequate thermal fatigue properties, strength, and wettability. [ 2 ]
Pin brazing is a metallurgically safe [citation needed] method of making electrical connections [1] to steel and ductile iron pipelines [citation needed] as well as other metallic structures, [2] which are to be cathodically protected or electrically earthed.
Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point.
For silver, copper-phosphorus and copper-zinc filler metals. For brazing copper and brass. Combusted fuel gas Decarburizing, AWS type 2, "endothermic generated atmospheres. 70–71% N 2, 5–6% CO 2, 9–10% CO, 14–15% H 2. For copper, silver, copper-phosphorus and copper-zinc filler metals.
Control rods can also be constructed as thick turnable rods with a tungsten reflector and absorber side turned to stop by a spring in less than one second. Silver-indium-cadmium alloys, generally 80% Ag, 15% In, and 5% Cd, are a common control rod material for pressurized water reactors. [6]
A better choice for vacuum systems is the tin-silver eutectic, Sn95Ag5 (Sn-Ag eutectic is actually 96.5-3.5); its melting point of 230 °C (446 °F) allows bakeout up to 200 °C (392 °F). A similar 95-5 alloy, Sn95Sb5, is unsuitable as antimony has similar vapor pressure as lead.
