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.
What is a scissor lift? A scissor lift is a type of aerial work platform used to lift personnel. These platforms extend and retract vertically with the help of the scissor linkages that fold in a crisscross manner. Scissor lifts are typically electrically powered although there are some that are powered by internal combustion engines.
Scissor-type ones are fine for smaller pieces of food. To use them, you have to slide one finger through a hole in one of the handles, as you do for scissors. Tongs whose holding ends have scalloped food-gripping parts can allow a more stable grip when lifting large items. For non-stick pans, you can get metal tongs that have plastic non-stick coating on the food-gripping parts, or nylon heads. Or, you can use wooden tongs.
