J.W. Harris 348-60R31 Rosin Solder 0.062 x 1 (Discontinued)

With some exceptions, these tin-lead solders can be used to join copper and most copper alloys, lead, nickel alloys and steel. Tin-lead solders are not recommended for joints subject to high stress or vibration in the cooling industry due to lack of sufficient elongation properties. These solders are also available with rosin or acid core. Similar to 50/50 but flows faster due to narrow melting range.
