The original flux-less alloy, does not need flux. Used for die attachment and attachment of metal lids to semiconductor packages, e.g. kovar lids to ceramic chip carriers. Coefficient of expansion matching many common materials. Due to zero wetting angle requires pressure to form a void-free joint. Alloy of choice for joining gold-plated and gold-alloy plated surfaces. As some gold dissolves from the surfaces during soldering and moves the composition to non-eutectic state (1% increase of Au content can increase melting point by 30 °C), subsequent desoldering requires higher temperature.[76] Forms a mixture of two brittle intermetallic phases, AuSn and Au5Sn.[77] Brittle. Proper wetting achieved usually by using nickel surfaces with gold layer on top on both sides of the joint. Comprehensively tested through military standard environmental conditioning.

Good mechanical properties, compatible with most metals, low vapor pressure, excellent fluidity when molten. Mostly used for brazing reactive metals, e.g. beryllium and titanium. Does not significantly alloy with nor wet iron. Rarely used alone due to relatively high cost.			100
Pd100	pure	1555[75]		Pure metal. High-temperature brazing of refractory metals.					100
Pt100	pure	1767	–	Very high temperature brazing. For refractory metals for high-temperature applications.						100
Cu100	pure	1085[1]	–	pure metal; CU 101 (99.90%), CU 102 or CDA 102 (99.95%), CU 103 (99%), CU 104 (99.90%, 0.015–0.040% P), BCu-1 or CDA 110 (99.99%). Free-flowing. Can be used for press fits. For ferrous alloys, nickel alloys and copper-nickel alloys. BVCu-1x is OFHC, vacuum-grade, for furnace brazing of steels, stainless steels and nickel alloys. Oxygen-containing copper is incompatible with hydrogen-containing atmospheres which cause its embrittlement. Cheaper than silver, but requires higher processing temperatures and is oxidation-prone. Used in fluxless vacuum brazing of stainless steels. High fluidity, low base metal erosion, extremely good wetting of steel. Relatively soft, which is beneficial for stress relief but impairs joint strength.	100
