OVERVIEW

Harris Silvalloy 45T: The Pro's Choice for Stainless

When your brazing project demands a perfect balance of flow, strength, and safety, reach for the Harris Silvalloy 45T. This 1 Troy Ounce coil of 1/16" wire is the ideal size for toolbox inventory, small repairs, or precision fabrication work. Known in the industry as a premium "problem solver," the 45T formula includes 45% silver and a touch of tin, which works magic on stainless steel and other difficult-to-wet metals.

Why choose 45T over standard silver solder? The secret is in the tin. It helps the alloy flow smoothly and wet out the surface faster, creating a seamless, leak-proof bond with less heat input. This is crucial when working with stainless steel to prevent overheating and discoloration. Plus, it is 100% cadmium-free, making it safe for food processing equipment, dairy repairs, and potable water systems. You get the performance of high-silver alloys without the health hazards associated with older cadmium-bearing rods.

Whether you are fixing a commercial kitchen mixer, brazing a custom stainless exhaust, or repairing brass fittings, Silvalloy 45T delivers a color match that blends in beautifully with white metals. Pair it with Harris Stay-Silv White flux for general applications or Black flux for longer heating cycles, and experience the difference a premium alloy makes in your brazing quality.

Why Welders Love It

  • Superior Wetting: The tin content makes it flow like water on stainless steel.
  • Safe & Compliant: Cadmium-free formula meets safety standards for food and medical use.
  • Gap Filling: A slight plastic range helps you bridge small gaps in imperfect fit-ups.
  • Versatile: Bonds steel, copper, brass, and bronze with equal strength.

FAQ

Silvalloy 45T contains tin (Sn), which improves wetting action on stainless steel and slightly lowers the melting range compared to standard 45% silver alloys without tin.

Yes, Harris Silvalloy 45T is cadmium-free and is suitable for use on food processing equipment where toxic metals are prohibited.

Yes, this is a bare wire coil. You must use a brazing flux, such as Harris Stay-Silv White or Stay-Silv Black, to prevent oxidation and allow the alloy to flow.

It has a solidus (starts to melt) of 1195°F and a liquidus (fully melted) of 1265°F.

No, silver brazing alloys like 45T are not suitable for aluminum. They are designed for copper, brass, bronze, steel, and stainless steel.

The 'T' typically indicates the presence of Tin in the alloy composition, which aids in wetting and flow characteristics.

This package contains 1 Troy Ounce (approximately 31.1 grams) of 1/16" diameter wire.

Yes, the high silver content provides a yellowish-white color that blends reasonably well with stainless steel, though it may tarnish slightly over time.
