Check below to see if your question is answered. Don’t see it here? Ask us! We’ll be sure to answer you quickly.

  1. Q. What is the difference between Ferrous Metal and Non-Ferrous Metal?
    Ferrous Metal contains iron. The word itself is derived from the Latin word Ferrum which literally means “iron”. Ferrous Metals include Steel and Stainless Steel.

    A Non-Ferrous Metal is any metal that does not contain iron. Common Non-Ferrous Metals are; Aluminum, Copper, Nickel, Tin, Lead, Zinc, and the alloy Brass.

  2. Q. Is there a difference between Aluminum Coiled Foil and Aluminum Coiled Sheet?
    ASTM International defines Coiled Foil as aluminum in thicknesses .0005” – .0059”, Coiled Sheets are aluminum in thicknesses .006” – .019”. Other terms of Aluminum Foil include Light Gauge referring to aluminum thicknesses .0001” – .00049” and Heavy Gauge referring to aluminum thicknesses .020” and above.
  3. Q. How are aluminum sheet and aluminum foil produced?
    Aluminum is passed between rolls under pressure, which makes it thinner and longer. Find out more about how aluminum sheet and aluminum foil are produced
  4. Q. Aluminum or Aluminium?
    In 1808 Sir Humphry Davy proposed the name aluminum for the metal; however, the name aluminium was adopted to conform with the “ium” ending of most elements. This spelling is in use in most countries. Aluminium was also the spelling in the U.S. until 1925, when the American Chemical Society officially decided to use the name aluminum instead.
  5. Q. What is the difference between Aluminum Foil and Tin Foil?
    Aluminum is often confused with tin, such as tin foil etc. Aluminum has replaced tin in most industrial applications, such as cans. Tin is considered to be toxic to humans whereas specific aluminum alloys have been FDA approved for direct and indirect food contact.
  6. Q. What is the difference between hard and soft foil?
    The lowest or basic strength of aluminum and each of its alloys is determined when the metal is in the annealed or soft condition. This is designated as the O (letter O) temper. For example, the annealed condition for alloy 1145 is written 1145-O. Annealing consists of heating the metal to the appropriate temperature for the correct period of time. The re-roll stock, from which foil gauges are produced, for example, is annealed prior to the rolling operations, so that it will be of maximum workability. All alloys can be annealed. All alloys also are strain-hardened and strengthened when cold worked, as in foil rolling. When the final product is wanted in the soft condition, it is given a final anneal.

    Because aluminum and certain of its alloys are strengthened beyond their basic strengths only by strain hardening, they are non-heat-treatable. Nearly all of the foil presently produced is rolled from non-heat-treatable alloys, which are given H number temper designations for the various specific strain-hardened conditions in which they are made. For example, common foil availability is alloy 1145-H19; the H1 means strain hardened, and the next digit indicates the degree of hardening, the 9 meaning full hard.
