Hafnium alloys: Part One

Pure hafnium is a lustrous, silvery metal that is not so ductile nor so easily worked as zirconium The electric conductivity is about 6% that of copper. It has excellent resistance to a wide range of corrosive environments.

Hafnium Alloys: Part Two

Hafnium, with a melting point of 2,233°C is a key member of the superalloy family with key usage in a range of extreme high temperature uses.
Possessing excellent mechanical and corrosion resistance properties, in combination with the ability to absorb neutrons, hafnium is a key constituent of nuclear reactor control rods.

Hardfacing Non-Ferrous Alloys

The prime function of Hardfacing materials is to protect a component or other material against the forces of wear.
Most hardfacing alloys are iron, nickel, or cobalt-base and can be used in a variety of forms including powder, solid welding rods or wires and tubular rods or wires.

High Strength Casting Copper Alloys

High strength casting copper alloys include cast aluminum bronzes and manganese bronzes.
Aluminum bronzes such as AB1 consist of two principal phases, alpha and beta, the iron addition appearing as a separate minor phase, while those alloys such as AB2, containing nickel and iron, have more complex structures.
High tensile brasses or manganese bronzes are alloys of copper and zinc in which the strength normally associated with straight copper-zinc-alloys is very considerably increased by the addition of elements such as aluminum, manganese, tin, iron and nickel.

High Strength Copper – Beryllium Alloys

Beryllium additions, up to about 2 wt%, produce dramatic effects in several base metals. In copper and nickel, this alloying addition promotes strengthening through precipitation hardening. In aluminum alloys, a small addition improves oxidation resistance, castability and workability. Other advantages are produced in magnesium, gold, zinc, and other base metals.

High Strength Copper-Titanium Alloys: Part One

Copper-titanium (Cu-Ti) alloys are emerging as ultra-high strength conductive materials that effectively replace conventional copper-beryllium (Cu-Be) alloys in applications such as conductive springs and interconnections. This transition has been accelerated by recognition of serious health hazards associated with beryllium-based production processes.
