Product Description

The corrosion resistant 4J36 capillary tube is an Invar alloy thin wall round tube available in customized sizes. This 4J36 alloy features an ultra-low expansion coefficient, excellent plasticity and toughness, and is suitable for both cold and hot processing.

Key Characteristics

Density: 8.1g/cm³

Iron-nickel alloy with ultra-low expansion coefficient

Excellent plasticity and toughness for easy processing

Corrosion-resistant in dry air at room temperature

Curie point at approximately 230℃ (ferromagnetic below, non-magnetic above)

Chemical Composition

Alloy	Ni	Cr	Fe	C	Mn	Si	Co	Mo	P	S
Invar 36	35-38%	≤0.5%	Balance	≤0.1%	≤0.06%	≤0.35%	≤1.0%	≤0.5%	≤0.02%	≤0.025%

Mechanical Properties

Tensile strength: 490MPa to 680MPa

Yield strength: ≥240MPa

Elongation: 25% to 35%

Brinell hardness (annealed): 130 to 180HB

Brinell hardness (cold rolled): 170 to 200HB

Preparation Process & Performance Optimization

The manufacturing process includes batching, smelting, casting, forging, heat treatment and precision machining. Heat treatment significantly impacts performance:

Annealing at 900°C for 2 hours stabilizes expansion coefficient at 1.2×10⁻⁶/°C

Aging treatment (300°C to 400°C) improves hardness and strength

350°C aging for 8 hours reduces expansion coefficient to 1.0×10⁻⁶/°C

Applications

Precision instruments (clocks, optical measuring equipment)

Aerospace components (satellite antennas, connectors)

Electronics industry (substrates, lead frames, shadow masks)

Medical equipment requiring high precision

Liquefied gas storage and transportation equipment
