Iron alloys - Import export

Tungsten has a high density, which makes it convenient for ionizing radiation shielding. Despite the higher density compared to traditional and cheaper lead, tungsten shielding is less heavy with equal shielding properties, and more effective if the weight is the same. Tungsten is a very refractory and hard metal, which makes it difficult to process. Therefore, more ductile tungsten alloys with nickel, iron, copper, etc. are used. Cr 16.0%-18.0% We buy alloys of the following grades: VN/VNZh alloys (category: Tungsten 12) (W - 80 - 90% Ni - 5 - 10% Fe - 1- 3%) VD alloys (W - 70 - 80% Cu - 20 - 30%)

Electrophoresis and Powder Painting is performed by a fully automated new generation painting system Pre-treatment Preparation of the surface to be painted is the key to successful painting, ensuring adhesion of the layer of paint and resistance to corrosion. Parts are pre-treated non-stop in a tunnel divided into eight stages, using environmentally friendly chemicals; the plant has already been prepared for use of the new nanotechnologies. Pre-treatments: Pre-degreasing Degreasing Rinsing Rinsing Activation Phosphatizing Rinsing Demi-rinsing Electrophoresis Electrophoresis painting is a painting surface treament which gives parts made of iron, steel and other alloys (electrical conductors) improved ability to resist corrosion. It is characterized by uniform depositing of epoxy resin on the surface of the part, ensuring long-lasting good protection against aggression from chemical agents and other factors; it also ensures improved adhesion of top coats of paint. Electrophoresis painting offers several important benefits: Uniform thickness and total covering of all parts, including sharp corners. Ability to control the thickness of the paint by adjusting application voltage and time and paint temperature. Thicknesses of 15 to 40 µ may be obtained, depending on the type of paint (the newest paints can even reach thicknesses of 60 ÷ 70 µ). Excellent resistance in saline mist tests, more than 500 hours, thanks to crystalline phosphatization pre-treatment. Good appearance and therefore top quality finish: the coating of paint is distributed perfectly over the surface. Following electroplating, treated elements are rinsed with ultra-filtered water at the rising unit in the circuit, permitting near-total collection of the paint that adheres to the elements but has not been electroplated. Electrostatic Powder Painting Powder painting is a surface finishing treatment for parts made of metal (aluminum, steel etc.) and alloys characterized by electrostatic application of powder paint which is then polymerized in a kiln. Powder painting prevents corrosion and makes the objects treated resistant to chemical and atmospheric agents. It also permits creation of a vast range of different surface colors and effects: orange-peel, embossed, hammered, etc. The powder painting procedure is ecologically sound because it significantly reduces risk to workers and the environment. Powder painting, electrophoresis or sanding: our mission is achieving excellence in our work through advanced technologies and careful choice of materials. This great care and commitment allows us to pass on the savings resulting from quality and durability to our customers.
