  • Tensile Strength, Ultimate Tensile Strength
    The maximum load, in tension, that a material can withstand before breaking. It is calculated as a breaking load for a standard cross section area and measured in Newtons per square mm (Nmm-2) or Mega-Pascals (MPa).
  • Tension Levelling
    Roller Levelling
    Flattening of sheet, strip or coil metal by passing it through a roll train staggered rolls. Levelling is achieved by precisely bending metal strip back and forth as it's passed through a series of small-diameter offset rolls. The material is usually also under tension loading.
  • Tin FoilCooking Foil, Foil, Kitchen Foil
    Cooking Foil, Foil, Kitchen Foil
    Cold rolled aluminium flat product less than 250 microns in thickness. Usage includes kitchen foil (cooking foil) and foil trays for food. Kitchen Foil is often incorrectly referred to as Tin Foil.
  • Tolerance
    The permissible limit, or limits, of variation to a specified parameter such as a dimension or weight per unit length usually expressed as 'plus' or 'minus' value on that quantity.
  • Tolerance
    The permissible limit, or limits, of variation to a specified parameter such as a dimension or weight, usually expressed as 'plus' or 'minus' value or percentage on that quantity.
  • Torsion Test
    A test in which a sample is twisted axially for a given number of revolutions. It may be conducted to destruction or to demonstrate that the material can withstand a specific amount of twisting.
  • Traffic Marks
    Fretting
    Abrasions, usually dark in colour, resulting from relative movement, or rubbing, between contacting metal surfaces during transit.
  • Triplate
    Transition Joint
    An explosively bonded bimetal flat bar that comprises a layer each of steel and marine-grade aluminium (alloy 5083) usually with an interlayer of pure aluminium. It is used for the on site welding of aluminium to steel, especially in shipyards and for offshore structures.
  • Tube Hollow, Hollow
    Interchangeable terms for a hot finished semi-finished product from either an extrusion or piercing process. They are the feedstock for cold drawing or cold reduced tube production.
