PLYMETAL
PRODUCTS
For applications where carbide is brazed to steel, it is often
desirable to use a strip product with a copper center. The copper
serves as an absorber of thermal expansion as well as shock. These
products are referred to as plymetals and are available in several
compositions.
#A50N Plymetal
A popular cadmium-free choice that delivers superb performance.
Silvaloy #A50N serves as the braze alloy. Melt Point = 1220°F
Flow Point = 1305°F
#2501 Plymetal
Uses Silvaloy #A40N2 as the braze alloy. It's cadmium-free and
provides good strength and wetting action on carbide. Melt Point
= 1220°F Flow Point = 1435°F
#5031 Plymetal
Used historically as the primary composition for joining carbide
to steel. It's use has become limited due to the presence of cadmium.
Displays exceptional strength and flow characteristics. Melt Point
= 1170°F Flow Point = 1270°F
CUSTOM
LAMINATES
In addition to our plymetal products, Bellman-Melcor delivers
precision custom laminates for a variety of uses. By layering
brazing or soldering alloys with base metals, an infinite combination
of precision engineered products are possible. Contact our technical
