8.6 Soft Solder Requirements According to JIS Z 3282-1986 (Soft Solder)

This Japanese industrial standard 089 Tin-Lead, Tin-Antimony, Tin-Silver, Tin-Bismuth, Lead-Silver, Tin-Lead-Silver light Tin-Lead-Bismuth is required for soft-soldering compounds. hereinafter referred to as “soft solder metal”

  1. Classification of solder metals

Types of solders are categorized according to their chemical composition as in Table 1.

  1. Quality

The quality of solder metal is as follows:

(1) Malleable solder shall be of consistent quality and free from defects that would adversely affect its use.

(2) The chemical composition is stated in Table 2 for Class 3 wire, Table 3 for Class A wire and Table 4 for Class B wire.

  1. Malleable solder symbol

Solder symbols include class, grade, form and size symbols. diameter (In case of bare welding wire and flat bar, the width size will be determined)

Soft solder There are several forms and are designated by abbreviation: rod (1), bare (B), flat strip (R), wire (W), custom form (F) and powder form (P).

8.7 Silver Brazing Filler Metals Specification Standard JIS Z 3261-1985 (Silver Brazing Filler Metals)

This Japanese industrial standard designates silver solder to be used for brazing.

hereinafter referred to as “hard solder” which

  1. Type of solder

There are 17 types of solder metals as shown in Table 1.

  1. Product Symbol

Details of products designated as symbols include the type of metal.

Hard solder, pattern and size Size of solder Based on the following format

– Free type (R) size, thickness x width

– Wire (W), size, diameter

– Wire rod (B) size: diameter x length

– Granules, powders and pastes (P) size is determined by the size of the metal powder grain size of the powder grain.

Defined as a “Mesh” unit, or possibly m, depending on the collusion.

8.8 Requirements for Copper and Copper-Zinc Brazing Filler Metals Standard JIS Z3262-1986 (Copper and Copper-Zinc Brazing Filler Metals)

This Japanese industrial standard The copper-copper-zinc solder is determined to be used for brazing, hereinafter referred to as “brazing brazing.

  1. Soldiers are divided into 11 types according to their chemical composition.
  2. Symbol of the product

The symbol of the product contains Which depends on the shape of the solder metal as follows

Types of solder, forms and sizes.

– Ribbon Band (R) Size – Thickness x Width

– wire (w) size – diameter growth

– wire rod (b) size – diameter x length grain, powder and paste (p) size is determined by the size of the metal powder grain.

The granule size is given in “Mesh” units or may be m depending on the agreement.

8.9 Requirements for Copper-Phosphorus Brazing Filler Metals JIS 2 3364-1985 (Copper Phosphorus Brazing Filler Metals) is a Japanese Industrial Standard. Designated copper phosphorus brazing alloy used for brazing In further detail, it will be called “Hard solder”
