Brief characteristics of zirconium

Zirconium is a strong, ductile and malleable metal with physical and chemical properties approximately similar to titanium. It has good corrosion and heat resistance. At elevated temperatures, the finely ground metal is capable of spontaneously igniting in air. The density of α at 20 °C is 6.5 g/cm³; melting point Tpl = 1855 °C. ZrO oxide has low thermal conductivity and high melting point.

Physical properties

  • Density - 6530 kg / m³;
  • Melting point - 1843 °C;

Mechanical properties

  • Tensile strength (after annealing) - 330 MPa;
  • Yield strength (after annealing) - 230 MPa;
  • Modulus of elasticity - 94,5 GPa;
  • Poisson's ratio - 0,34;
  • Relative elongation at break (after annealing) - 32%; Brinell hardness
  • Brinell hardness (transformed from Vickers hardness for 3000kg / 10mm bead; sample after annealing) - 145NV;

Hardness

  1. Rockwell hardness, scale A (converted from Vickers hardness; sample after annealing) - 49;
  2. Rockwell hardness, scale B (converted from Vickers hardness; sample after annealing) - 78;
  3. Vickers hardness annealed sample - 150;

Buy a range of rare earth metals at prices from the manufacturer offers the company Evek GmbH. The supplier guarantees immediate product delivery to any location specified by the customer.

Thermophysical properties

  • The coefficient of thermal expansion for the temperature range of 20-100 ° C - 5.80 μm / m ° C;
  • Thermal conductivity 16.7 W / mK - 116;

Production

Zirconium is manufactured to the following foreign standards ASTM :

  • B493;
  • B494;
  • B523;
  • B550;
  • B551;
  • B653;
  • B658;
  • A5.24.

Fabrication, machining and heat treatment

Zirconia must be carefully handled because zirconia powder and chips are easily flammable. Consequently, machining requires the use of coolant, and cutting should be done at heavy feed and low cutting speeds. Zirconia is ductile and easy to machine. However, proper lubrication must be used to prevent wear on the deforming tool. The tungsten arc gas welding method is best suited for zirconia welding. Proper shielding is required for zirconium welding, otherwise it can result in weak and brittle welds.

Applications

  • Jet Engines;
  • Knife blades:
  • Water-cooled nuclear reactors;
  • Superalloys;
  • Chemical processing equipment.
