TIN PLATING SERVICES TO THE FOLLOWING SPECIFICATIONS

MAF specilizes in tin plating for telecommunications industries

MIL-T-10727

Type I: As specified on drawing.

Thickness guide (not part of spec.) as follows:
Electrodeposited – Use ASTM-B-545 as guideline.

If not specified, bright will be generally provided.

Please note: This specification is provided for reference purposes only as it has been super-ceded by ASTM-B-545 (See below).

.0001-.00025″	Flash for soldering
.0002-.0004″	To prevent galling and seizing
.0003 min.	Where corrosion resistance is important
.0002-.0006″	To prevent formation of case hardening during nitriding.

Type II: Hot dipped (not currently available at MAF)

ASTM-B-545

Types are matte, bright, or flow-brightened

Class A: .0001″ min
Class B: .0002″ min
Class C: .00032″ min .0004″ min. for steel
Class D: .0006″ min .0008″ min. for steel.

Class E: .0012″ min

ASTM requires purchaser to supply information, such as base metal, under plating, test requirements and test methods etc. In general, copper alloys containing more than 5% Zn shall have a copper undercoating of at least 0.0001″ or nickel undercoating of at least 0.000050″.

This specification applies to electroplated coatings of not less than 99% tin (except where deliberately alloyed with lead per customer drawings and/or P.O requirements).

Tin 88-98%, remainder lead.

ITEMS OF NOTE

The final product in plated condition will possess a gray-white color and a very high luster in fused condition.

Tin plating produces a soft, but very ductile surface and displays good corrosion resistance. (Coated items should meet 24 hour 5% salt spray requirement).

We DO NOT recommend tin for low temperature applications as it changes structure and loses adhesion when exposed to temperatures below -40º C.

We plate directly on steel substance (no undercoating for steel unless otherwise specified).
