1. Cost Factor: Aluminium bo no sua koraa sen kɔbere de no. Enti, aluminium a wɔde di dwuma sɛ nneɛma a wɔde yɛ nhama a ɛwɔ soro no yɛ nea ɛho ka sua wɔ ɛka a wɔbɔ mu, a ɛboa ma anyinam ahoɔden nhyehyɛe no nyinaa adansi ne ne siesie ho ka so tew.
Nea ɛto so abien no, emu duru ne ne kɛse: Aluminium no mu duru yɛ kɔbere nkyem abiɛsa mu biako pɛ, a ɛkyerɛ sɛ wɔ ne tenten tebea koro mu no, aluminium hama no mu duru sua koraa sen kɔbere nhama no.

Nnɛyi mfiridwuma a wɔde yi aluminium na wɔyɛ no ama aluminium nhama a ɛma anyinam ahoɔden no abɛn kɔbere no. Enti, sɛ yɛhwɛ anyinam ahoɔden a, aluminum nhama betumi adi ahwehwɛde ahorow no ho dwuma koraa.
