Refractory Metals

Metals – Dale Engineering

Dale Engineering is a full service precision CNC machine shop specializing in small to medium size components made from Molybdenum, Tungsten and other exotic metals. We are located in Bedford, Massachusetts and some of the industries we service are: Medical, Bio-tech, Electronics and Semi-Conductor Industries.

Molybdenum is a transition metal which is providing a practical alternative to more familiar traditional metals. The low thermal expansion of molybdenum, similar to that of silicon, makes it a frequently used material in the electronics industry for semiconductor supports and glass sealing. Due to its excellent thermal conductivity and low resistivity, molybdenum is also used widely in the furnace industry for radiation screens, elements and sintering trays. Molybdenum has good corrosion resistance particularly to hydrochloric acid. Unlike tantalum, niobium, titanium and zirconium; molybdenum is not subject to hydrogen embrittlement. With all this in mind, Molybdenum is the metal of choice for Dale Engineering and its customers.

Because of its exceptional properties, tungsten carbide has, in recent years, emerged as the superior alternative to steel for many industrial applications. Tungsten carbide is a ceramic material composed of approximately a 1:1 ratio of tungsten and carbon atoms. Thanks to its wear resistance and hardness, tungsten carbide is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions such as high temperatures, corrosion and abrasion. The primary attraction of tungsten carbide is its high strength and low ductility at high temperatures. Because of its longer wear qualities, tungsten carbide tooling translates into one of the best options for Dale Engineering and its customers.
