According to the processing method, Aluminum alloy can be divided into two major types: deformation of aluminum and cast aluminum alloy.
Deformed aluminum grades are represented by four digits, which contain the proportion of alloy components. The four-digit number after the dash represents the type of heat treatment, such as "6061-T6".
Aluminium is primary among the factors that reduce plant growth on acid soils. Although it is generally harmless to plant growth in pH-neutral soils, the soils of toxic Al3+ increase .
Most acid soils are saturated with aluminium rather than hydrogen ions. The acidity of the soil is therefore, a result of hydrolysis of aluminium heatsink supplier
. The concept of "corrected lime potential" is now used to define the degree of base saturation in soil testing to determine the "lime requirement".
Wheat has developed a tolerance to aluminium, release of organic compounds that bind to harmful aluminium cations. Sorghum is believed to have the same tolerance mechanism. The first gene for aluminium tolerance has been identified in wheat. It was shown that sorghum's aluminium tolerance is controlled by a single gene. This adaptation is not found in all plants.
