In brass brand L68 intended for the production of special purpose products, the mass fraction of elements should not be more iron — 0,07%, antimony — 0,002%, phosphorus — 0,005%, arsenic — 0,005% sulphur — 0.002% of the (sum of other elements is 0.2%). The brass brands of l96, L90, L80, L70, L68, L63, L60 allowed mass fraction of Nickel up to 0.3% by mass fraction of copper, which do not take into account the amount of other elements. In brass all brands in coordination with the customer to determine the mass fraction of tin, aluminum, manganese and silicon, the values of which take into account the amount of other elements. In brass grade L70, used for the production of condenser tubes and heat exchangers allowed arsenic to 0.06% by mass fraction of copper, which do not take into account the amount of other elements. In brass brands L63, used in the food industry, the mass fraction of lead should not be more than 0.05%. For non-magnetic alloys, the mass fraction of iron should not be more than 0.03%. |
Supplier — the company Avecho offers various types of products from alloys of brass domestic and foreign production that meets the requirements of the standards. Products are offered at affordable prices from the manufacturer. Supplier guaranteed timely delivery at any address specified by the consumer.

In the complexly alloyed brass grades except LAN59−3-2, L75mk, LA77−2U, is allowed the mass fraction of Nickel up to 0.5%, which is not included in the total amount of other elements, and is counted as the mass fraction of copper. In brass brand Lmc58−2 at the customer’s request mass fraction of manganese is set in the range of 3.0%-4,0%. In brass LKBO62−0,2−0,04−0,5 mass fraction of boron content should be within the range of 0.03% to 0.10%, which does not include the amount of other elements. In brass brand LA77−2U mass fraction of iron less than 0.03% is not a rejection symptom. In brass brand Lamsh77−2-0,04 total mass fraction of phosphorus and arsenic should not be more than 0.04%. Manufacturer of brass stamps Lomsh70−1-0,04 permitted without the mass fraction of arsenic. |
Supplier — the company Alekhlas — offers to purchase assortment of various brass alloys Russian and foreign production. Products can be purchased at a price formed on the basis of European and world standards. Possible, wholesale and retail, for regular customers a flexible system of discounts.
