The density, specific heat, melting point of lead.
Electrovek-steel company offers to buy lead at an affordable price of the manufacturer, the characteristics of which meet the requirements of GOST 3778−98. The supplier guarantees prompt delivery of products to the address specified by the customer.
General characteristics of metal
Freshly melted lead usually has a bluish-gray color with a glow, but when in air, the metal quickly fades, which is associated with the formation of an oxide surface film. At the break of lead, its crystalline structure of gray color is clearly visible.
Lead is often used as a metal for a variety of laboratory studies, because it is very soft, and by rheological properties is close to steels. Easily fuses with other metals, forming stable alloys, whose properties can be very different from pure lead (for example, amalgam-lead-mercury-liquid alloy). Pairs of lead are toxic, and prolonged contact of the metal with the skin of the hands often causes allergic reactions.
Buy at an affordable price for the laboratory and industrial purposes the company offers Electrovek-steel. The supplier guarantees the timely delivery of the products to any address indicated by the customer.
Physical properties of lead
Lead, which meets the technical standards of GOST 3778−98, must have the following physical characteristics:
Density, kg / m 3 :
In a solid state at 20 ° C… 11340
In the liquid state at the melting point… 10300
Temperature, ° С:
From the mechanical characteristics of the metal should be noted the following:
- Temporary resistance to tearing, MPa… 12… 13
- Elongation at elongation,%… .50… 70
- Brinell hardness, HB… 3.2… 4.8
Cold deformation of lead does not lead to a change in its mechanical properties due to the low recrystallization temperature of the metal, which after rolling is 35… 40 0 С.
The company Electrovek-Steel offers at affordable prices lead of any brands. Supplier provides prompt delivery of products to any point set by the customer.
