Phynox is Cobalt-Chrome-Nickel alloy. Phynox is an alloy with high strength, ductile and good mechanical properties.

Phynox can be hardened by aging. Phynox also has excellent fatigue life and corrosion resistance in numerous environments and is not magnetic.

Phynox is used in places where temperatures up to 380 ° C (715 ° F) are required for corrosion and high durability.

Phynox is mainly used in; medical devices, dental products, surgical implants and orthopedics.

Phynox (AFNOR, K13C20N16Fe15D07) is a cold-working austenitic alloy and has the ability to additionally cure by aging at a moderate temperature (about 500 ° C). The elastic modulus in the fully hardened state is 210 000 MPa and the UTS levels in the cold rolled strip are up to 2500 MPa.

In addition to its very high yield strength, Phynox offers a variety of physical, chemical and technological properties suitable for a wide range of applications.

PHYNOX’S DISTINCTIVE FEATURES:

• Outstanding resistance to corrosion
• Good fatigue strength
• Absence of magnetism
• Can be used in a wide temperature range from liquid helium to about 500 ° C
• Perfectly compatible in contact with human tissues
• Possibility of increasing the strength of the parts after aging by forming hardening, possibility of causing strength levels that can not be obtained with other materials
• Lack of fragility at low temperatures

A working temperature of about 100 ° C higher than stainless steel

Molybdenum-containing stainless steels to be superior to corrosion resistance

Phynox often provides the best solution when high mechanical performance is required in extremely corrosive operating conditions.

Phynox finds numerous applications in clock construction, surgical implants, meteorology, electronics and aerospace engineering:

PHYNOX MAIN APPLICATION AREAS

• Clock motor springs
• Navy equipment
• Shaped springs (spiral, etc.)
• Weaponry
• Flexible couplings
• Osteosynthesis prostheses
• Electrical and electronic equipment
• Heart battery
• Equipment for the chemical and oil industry
• Special collar for missiles
• Aviation and spacecraft
• Automotive ABS systems
• Automotive injection systems
• Surgical implants and medical devices
• Various diaphragms
• Printer springs

PHYNOX HEAT TREATMENT

Standard final aging is 3 hours at 520 ° C.

The heat treatment in the air does not change its mechanical properties, but it disrupts its appearance and the metal gets a pale yellow color. Operations under a vacuum of 10-5 torrents or in a neutral atmosphere (eg, Argon) are recommended.

PHYNOX CORROSION RESISTANCE

Phynox is not sensitive to corrosion by organic acids and has excellent resistance to salt spray tests. Its behavior in inorganic acids is superior to the best stainless steels.

In addition, due to its underlying passivity to human tissues, Phynox is used for artificial bone implant (cast and forged prostheses).

PHYNOX PROCESSING

The mechanical properties in the annealed delivery condition are similar to the other austenitic alloys.

Since the Phynox work is strongly hardened, machining should preferably be done with carbide tools. For large tilt angles, a moderate cutting speed should be used.

Phynox can be processed electrochemically.
