Standards

CMC has developed and implemented a quality management system (ISO 9001/2000) to demonstrate its capability to consistently produce products that meet applicable regulatory and industry requirements.

We ensure consistent client satisfaction through effective application of ISO 9001/2000 and ongoing improvement.

CMC is Controlled Goods Registered under CGP #17064 - valid until February 2017.

Our operations are in compliance with the following industry specifications for electroless nickel:

► Consensus Standards

ASTM B-733
ASTM B-607
Mil-C-26074E (AMS-26074): a military specification, approved for use by all Departments and Agencies of the Department of Defense
AMS 2405
AMS 2404
AMS 2399

► In-House or Proprietary Standards

Ford: ESW-M1P65A
Chrysler: PS-5009
GM
Aircraft companies: Boeing, Pratt Whitney
Machinery equipment companies: Caterpillar, Applied Materials

► Specification Requirements for Mil-C-26074E Classification

Nickel coatings shall be classified in accordance with thermal treatment applied subsequent to plating:

Class 1: As plated, no subsequent heat treatment: a bake for hydrogen embrittlement relief is not considered a heat treatment.

Class 2: Heat treated to obtain required hardness. May be used on all metals not affected by heating to 500F and above. Coatings shall have a minimum hardness of 800 knoop or equivalent vickers when tested. Class 2 coatings on steel parts that have a hardness of 40 RCH or above are required to be tested without cracking of fracture. The desired hardness can be achieved by heating the part (see within 4 hours arter coating).

Class 3: Aluminum alloys non heat-treatable, and beryllium alloys processed to improve adhesion of the nickel deposit. Non heat-treatable aluminum parts shall be heated for 1 to 1.5 hours at 375F to improve adhesion of nickel deposit.

Class 4: Aluminum alloys, heat-treatable, processed to improve adhesion of the nickel deposit. Heat-treatable aluminum alloys shall be heated between 240F to 260F for 1 to 1.5 hours to improve adhesion of nickel deposit.

* NOTE: These alloy types and grades may undergo microstructural changes when heated to 375F.

Nickel coatings have the following grades:

Grade A - O.0010-inch minimum thickness.
Grade B - 0.0005-inch minimum thickness.
Grade C - 0.0015-inch minimum thickness

► ASTM B-733

A standard specification for autocatalytic nickel-phosphorus coatings on metals.

Type 1: No requirement for phosphorus
Type 2: 1-3% P low phosphorus
Type 3: 2-4% P low-med. phosphorus
Type 4: 5-9% P medium phosphorus
Type 5: 10 % + P high phosphorus

QUALITY Requirements for ASTM B-733:

Appearance;
Thickness - service condition;
Adhesion - testing method ASTM B571;
Porosity;
Composition - alloy type;
Microhardness - ASTM B578;
Wear;
Hydrogen embrittlement evaluation ASTM F519; and
Corrosion resistance.
