Overview of Spherical Metal Powder Iron Nickel Alloy 4J36 Powder

Spherical Metal Powder Iron Nickel Alloy 4J36 Powder comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.

Key Characteristics of Spherical Metal Powder Iron Nickel Alloy 4J36 Powder

  1. Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.

  2. Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.

  3. Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.

  4. Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Spherical Metal Powder Iron Nickel Alloy 4J36 Powder

4J36 is a specific type of nickel-chromium (Ni-Cr) alloy, often referred to as Invar 36 due to its low coefficient of thermal expansion, making it suitable for precision applications where temperature stability is crucial. Here are some key parameters for spherical metal powder, specifically iron-nickel alloy 4J36:

1. Composition: 4J36 typically consists of approximately 47% Nickel (Ni), 42% Iron (Fe), and the remaining balance usually consists of carbon (C), chromium (Cr), and small amounts of other elements like manganese (Mn) or molybdenum (Mo).

2. Chemical Formula: Ni-Fe-Cr (with minor additions)

3. Mechanical Properties:
– Tensile Strength: 100-120 MPa (about 14,500-17,300 psi)
– Yield Strength: 80-90 MPa (about 11,600-13,100 psi)
– Elongation: 20-30%
– Hardness: Rockwell B-scale (HB) around 85-95

4. Thermal Properties:
– Coefficient of Thermal Expansion (CTE): Very low (< 10 parts per million per degree Celsius), which makes it dimensionally stable over a wide temperature range.
– Magnetic Properties: Non-magnetic in the annealed state but can become slightly magnetic when cold-worked.

5. Heat Treatment: 4J36 is commonly heat-treated to achieve the desired properties. Annealing at temperatures between 860°C to 960°C (1580°F to 1760°F) followed by air cooling is typical.

6. Applications: Spherical 4J36 metal powder finds use in various industries such as aerospace, military, medical devices, and precision engineering, where components need to maintain their shape and alignment over a wide temperature range.

Please note that exact values may vary depending on the manufacturer and the purity of the material. It's essential to consult the supplier for the most accurate specifications.

FAQs of Spherical Metal Powder Iron Nickel Alloy 4J36 Powder

Q1. What exactly is Spherical Metal Powder Iron Nickel Alloy 4J36 Powder, and how is it different from solid metal?

Spherical Metal Powder Iron Nickel Alloy 4J36 Powder consists of tiny particles of pure metals or metal alloys. Unlike solid metal, which exists as a continuous mass, metal powder offers increased surface area, making it more reactive and easier to form into complex shapes through processes like sintering or 3D printing.

Q2. How is Spherical Metal Powder Iron Nickel Alloy 4J36 Powder produced, and what are the common production methods?

Spherical Metal Powder Iron Nickel Alloy 4J36 Powder is typically produced through several methods, including:

– Atomization: Molten metal is sprayed into fine droplets that cool and solidify into powder.

– Chemical reduction: Metal oxides are reduced to their elemental state to form powder.

– Electrolysis: Electrical current is used to deposit metal onto a cathode, later harvested as powder.

– Mechanical processes: Large metal pieces are milled or ground down into powder.

Q3. What factors determine the quality and suitability of metal powders for different applications?

Quality and suitability depend on factors like:

– Particle size and distribution: Affects flowability, packing density, and final product properties.

– Composition and purity: Determines the material’s properties and its appropriateness for specific uses.

– Shape: Spherical powders for better flow, flake shapes for coatings.

– Density and porosity: Influences strength and other mechanical properties.

Q4. What safety precautions should be taken when handling metal powders?

Safety measures include:

– Wearing personal protective equipment (PPE) like gloves, goggles, and respirators.

– Storing powders in airtight containers away from moisture, heat, and ignition sources.

– Using explosion-proof equipment in processing areas.

– Ensuring proper ventilation to avoid dust accumulation and inhalation risks.

– Following strict handling procedures to prevent spills and cross-contamination.

Q5. How are Spherical Metal Powder Iron Nickel Alloy 4J36 Powder used in the manufacturing industry?

Spherical Metal Powder Iron Nickel Alloy 4J36 Powder find applications in:

– Powder Metallurgy: To create parts by compacting and sintering, ideal for mass production of complex components.

– Additive Manufacturing (3D Printing): Layer-by-layer construction of parts for customized and intricate designs.

– Thermal Spray Coatings: Applying protective or functional coatings to surfaces for corrosion resistance, etc.

– Electronics: Precious metal powders in conductive pastes, connectors, and other components.

– Chemical and Catalyst Industries: As catalysts due to their high surface area, promoting chemical reactions.

Q6. Are Spherical Metal Powder Iron Nickel Alloy 4J36 Powder recyclable or reusable?

Yes, Spherical Metal Powder Iron Nickel Alloy 4J36 Powder can often be recycled or reused. Unused powder or scrap from manufacturing processes can frequently be collected, reprocessed, and reintroduced into production cycles, contributing to sustainable manufacturing practices.

Q7. How does the cost of Spherical Metal Powder Iron Nickel Alloy 4J36 Powder compare to traditional metal forms?

The cost depends on factors like the metal type, production method, and purity.
