Corrosion properties of tin
Are you interested in the corrosive properties of tin from the supplier company AvecGlob? Here you will find the necessary information on this topic.
general information
Tin is a non-toxic metal that is easily processed and has several useful characteristics, some of which are low melting points, ductility, resistance to corrosion and fatigue, and the ability of an alloy with other metals. Tin is used in the production of tin (with a coating of tin) used for food packaging, as an alloy for the supporting metal, and as an alloy in metal coatings.
The role of tin as an alloy with lead in solder increases due to the environmental hazard of lead. Tin is also used as an alloy for bearing metal, and also as an alloy in metal coatings. The most important tin ore is cassiterite (SnO 2), although small amounts of tin are extracted from sulphide minerals, such as stannite (Cu 2 FeSnS 4).
Supplier — AvekGlob Company — offers various types of products from tin of domestic and foreign production, which meets the requirements of standards. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Basic dependencies
The appearance of corrosion in conditions of high temperature and humidity can be the cause of the growth of threadlike crystals — tin antennae. Especially intense can be corrosion of tin-copper alloys, which contain up to 5% tin.
Tin alloys, applied as a surface coating on a copper base, should not be stored at elevated temperature and humidity (85 ° C / 85% RH). Various grades of tin-copper alloys show differences in the growth trends of whiskers.
To determine the relationship between the formation of whiskers and the decrease in the corrosion resistance of tin, polarization measurements are carried out. Corrosion behavior of the layers is also studied in the cross sections of tin alloys.
The probability of reducing the corrosion resistance of tin depends on three main factors: the corrosion resistance of the finish of the product surface, the rate of expansion of the corrosion product and the rate of recrystallization of tin or tin alloy.
Supplier — AvekGlob Company — offers to purchase tin in a wide range of profiles and technological applications. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
