To prevent transport damage, all goods are securely packed in either cardboard boxes or wooden cases, with appropriate internal protection.

Resistance heating alloys are available in a variety of delivery forms, including wire spools, pails, coils, and strips, to cater to diverse customer requirements. Each delivery form is designed to optimize handling and storage, with standardized sizes and lengths detailed for convenience. Surface finishes, dimensions, and resistance tolerances are carefully controlled, with the option for closer tolerances upon request. This chapter outlines the available delivery forms and specifications, ensuring reliability and ease of use for various applications.

Wire

Wire with a diameter of ≤1.63 mm (0.064 in) is delivered on spools, as shown in the figure. Each spool contains a single continuous length of wire.

Wire sizes ranging from 0.40 mm to 1.63 mm (0.016–0.064 in) can also be supplied in round pail packs (drums), as shown in the table below.

Wire with a diameter greater than 1.65 mm (0.065 in) is typically supplied in coils with an inner diameter of approximately 500–600 mm (19.7–23.6 in).

Wire with a diameter of less than 1.82 mm can be supplied on standard spools. Each spool holds one continuous length of wire.

Delivery tolerances

Cold-drawn round wire is supplied with a resistance tolerance of ±5% per length. Cold-rolled strip is also supplied with a resistance tolerance of ±5% per length. Wire and strip can be supplied with closer tolerances upon request.

Important

Tolerances on dimensions and resistance per unit length must not be specified simultaneously.
