add brand to image alt tag

Hi, first let me thank you for this great plugin.
i’d like to use this code to add automatically product name and product brand to the alt text of images. `add_filter(‘wp_get_attachment_image_attributes’, ‘change_attachement_image_attributes’, 20, 2);

function change_attachement_image_attributes( $attr, $attachment ){
// Get post parent
$parent = get_post_field( ‘post_parent’, $attachment);

// Get post type to check if it’s product
$type = get_post_field( ‘post_type’, $parent);
if( $type != ‘product’ ){
return $attr;
}

/// Get title
$title = get_post_field( ‘post_title’, $parent);

$attr[‘alt’] = $title;
$attr[‘title’] = $title;

return $attr;
}`
is there a way to get the product brand ?
Thank you very much
